In terms of IT, design means much more than just creating visuals for a digital solution. Specifically, while the concepts of UX and UI design have long been familiar to anyone who is at least a little involved in software product development, the "product design" term is a relatively new one. Based on its name, we can already make a preliminary conclusion that the work of product designers involves something more than creating a visual for a product, but what exactly? Let's figure it out right now.
What Is UX Design?
UX design is everything that is aimed at the end user getting a certain experience/impression from interacting with the interface of your solution. Its quality can be measured by whether the user manages to achieve the specific goal, and how easy and pleasant it is for him/her.
Usually, the UX design process includes the following stages:
End-user research;
Building information architecture;
User flow creation;
Creating visuals;
Ensuring the convenience and accessibility of the created solution.
Let's dwell on these stages in more detail.
Key Elements of UX Design
So, below we will consider the above stages (elements).
End-user research. It all starts with a survey of the target audience representatives to understand their needs, desires, and pain points. Then they are provided with raw prototypes for testing so that specialists can identify typical problems and imperfections in their concepts.
Building information architecture. The next step of UX product development is to build low-fidelity wireframes that demonstrate the hierarchy of the product’s elements and functions. After that, designers build an information architecture, which implies dividing the content into categories that simplify the search for information.
User flow creation. Now, everything is ready to recreate the sequence of steps that the user must take to achieve the goal with the help of a specific product. After the main steps are reproduced, microinteractions have to be implemented – we mean system feedback that improves the quality of the user experience. Additionally, the product is analyzed in accordance with the WCAG 2.0 guidelines – this is necessary for its accessibility for people with disabilities.
Creating visuals. At this stage, specialists create the visual part of the user interface including the color palette, icons, typography, etc., and also ensure consistency with the previously created templates.
Ensuring the convenience and accessibility of the created solution. To assess the convenience of the created solution, designers usually use a heuristic approach. Also, they check compliance with the required WCAF 2.0 level. If significant deficiencies are detected, the product is returned for optimization.
Why Is UX Design Important?
UX design services are primarily focused on ensuring end-user satisfaction with the product – that is, it means that the product is comfortable to use and intuitive, and, in general, allows users to quickly complete the tasks assigned to it. In the long term, a properly created UX design can provide a boost in business revenue, an expansion of its consumer base, an increase in competitive advantage, a reduction in the expenses on regular business operations, and many other things. Ultimately, it is important to understand that all this is a necessary but not sufficient condition for the product success.
UX vs. UI Design
Many people don’t understand the user experience vs design difference. However, while UX product design is aimed at creating a positive user experience when interacting with a product, the UI design is about creating a certain, aesthetically attractive appearance and conveying specific feelings to the end user through it.
What Is Product Design?
Now, let's talk about product design: it is a much more comprehensive term than UX and UI design. It ensures that users do not just enjoy dealing with a specific software solution – instead, they should help the owner of this solution achieve specific business goals through this interaction.
Key Elements of Product Design
To better understand the product design vs UX design difference, we suggest, as in the previous case, to consider the key stages of the first term.
Planning. It starts with comprehensive market research: analyzing its trends, identifying competitors’ advantages and disadvantages, defining the target audience, etc. After that, specialists must align the client's business goals with the collected information and develop a product roadmap (this is performed in collaboration with other project team members).
Ensuring end-user focus. Now, having information about the target audience at hand, specialists can create user personas by using their demographics, behavioral patterns, pain points, needs, etc. After that, they begin to build user flows and optimize them through testing.
Interface design. This stage of the product design process involves creating medium-fidelity prototypes that not only describe user interactions with individual interface components but also contain microinteractions and visual detailing.
Interaction with the project team. Typically, product designers work in teams that work according to the cross-functional methodology – here, they are encouraged to work closely with specialists from other areas. This allows them to reach alignment on goals and their achievement. At this stage, they use prototypes, which, as their details are agreed upon, specialists optimize into a full-fledged product design.
User feedback analysis and optimization. Finally, the completed solution is presented to end users (depending on the stage of development, these can be representatives of a focus group or real users) to obtain and process their feedback. After that, the obtained insights are gradually implemented through optimization of the presented version.
Why Is Product Design Important?
Its importance is hard to overestimate: product designers collaborate with other members of the project team throughout its life cycle, thereby ensuring the joint achievement of the goals set by its owner. Even though, as in UX design, the convenience of the user’s interaction with the product also plays an important role, it is perceived as something more global – something that is aimed at solving specific problems within one business.
UX Design vs. Product Design: the Differences
From all of the above, we can conclude that the main goal of product design services is to create a comprehensively successful product: that is, one that surpasses its competitors in some way and satisfies the client's business needs, the specifics of their business niche, the needs of the target audience, market trends, etc. This, in turn, imposes on product designers the need to participate in all stages of product development.
As for UX design, its task is to make the product user-oriented, without covering or only partially covering the business aspects declared by the product owner. Thus, without thinking about the need for product design and implementing the UX design stage only, you can lose sight of the factors that hinder the long-term product’s viability on the market (in particular, this often happens with startups and projects with a non-standard approach to solving ordinary problems).
Conclusion
Now, knowing the difference between the two above concepts, you can understand who exactly your team needs – a UX/UI service provider or a product designer. Whichever option is closer to you, you can always contact us, and we will select a specialist according to your project requirements or assemble a team that will accompany you from collecting project requirements to its launch and optimization.
What is the main difference between product design and UX design?
Product design focuses on the entire lifecycle of a product, ensuring that it meets business goals and user needs. UX design, on the other hand, focuses on creating a positive user experience.
Why is UX design important?
UX design ensures a product is user-friendly, intuitive, and enjoyable. Good UX design can increase customer satisfaction, drive usage, and improve business outcomes such as revenue and customer loyalty.
How does product design benefit a business?
Product design helps align the product with business goals, ensures it meets market needs, and works to differentiate the product from competitors. This comprehensive approach can lead to better market performance and user satisfaction.
How does UX design differ from UI design?
UX design concerns the overall user experience with a product, while UI design focuses on the look and feel, creating an aesthetically pleasing interface.
In 2024 alone, the medical imaging software market size reached $8.11B. By 2029, it is projected to grow to $11.83B and up to 7.84% at a CAGR. This is a fairly predictable trend due to the development of AI. Especially since big data, cloud technologies, and other advancements are already significantly speeding up the accuracy of diagnostics.
If you are considering custom development of medical image analysis software, now is the most favorable time. Below, we will reveal the specifics of creating such solutions and describe the requirements and the challenges you may face.
What is the definition of medical imaging software?
Medical imaging software—it's the digital tool doctors use to examine medical images. Think X-rays, MRI and CT scans, ultrasounds, PET, and other radiology scans. Basically, it helps to see the details of every complex illness and make informed decisions about patient care.
To maximize efficiency, medical imaging software integrates a range of advanced technologies. These include AI for anomaly detection, ML for image segmentation, and methods for filtering, contrast enhancement, and noise reduction to improve image quality.
Also, 3D reconstruction technologies create volumetric models of organs and tissues. Developers also rely on the DICOM standard for medical images as it allows seamless transfer. They also use cloud tech to access data, integrated medical records, and VR and AR to visualize data and create interactive interfaces.
As a result, with medical image analysis software, healthcare organizations reduce the workload of their doctors and researchers and minimize the likelihood of misdiagnosis.

Medical imaging software development: Steps to follow
Custom development must follow clearly defined stages that most teams use. But, it can still be approached in various ways. Below, we outline how healthcare software development services are delivered in our company.
Concept formation
Start your medical imaging software project with market analysis. Define the target audience, prioritize tasks the software should solve, and research competitors (to identify their strengths and weaknesses). Based on the insights, our medical imaging software development team assesses the functional requirements and evaluates the need for specific technologies to handle image processing. This ensures that the chosen solutions align with the project's technical needs and optimize the processing of healthcare-related images.
Planning
Once we agree on the conditions with all stakeholders, we will write a technical specification for your medical imaging software. This document will describe its functionality, interface, API, security, and integration requirements. We will also approve the tech stack and necessary integrations. Finally, we create a roadmap that defines the milestones and deliverables for each medical imaging software development project stage.
Prototyping
Now that everything is ready, we can begin creating user stories. They include handling DICOM file uploads and 3D models, among other key tasks. For UX/UI best practices of safe data, we follow the WCAG 2.1 guidelines. They ensure accessibility for users with varying technical skills. We also test prototypes with focus groups to see feedback on complex features, which is helpful for future design improvement. Finally, after the edits are done, we develop a full-fledged design.
Coding
The frontend has algorithms to process and analyze medical images. The backend ensures secure data transfer between the medical imaging software and storage. It also encrypts data and protects against vulnerabilities like SQL injections. These involve writing database queries for smooth software interactions and data storage interactions. And last but not least—we also integrate with your healthcare org's existing systems and services (if any).
Testing
Once the code for your medical imaging software is ready and all components have passed unit tests, we run complete test cases. We check for load, functional, non-functional, security, and usability issues.
Deployment
At this stage, we are choosing hosting for your medical imaging software (usually either cloud or local servers), setting up CI/CD, and training end users, for example, by providing them with documentation, training materials, or live courses. Once we've done it, we deploy the solution (first in the test environment and then—in the actual usage environment).
Support and updates
Finally, after the medical imaging software is deployed, we set up monitoring systems to track its performance and detect errors, fix post-release bugs, optimize it according to user feedback, and add new features if required.
Key tech specifications for medical imaging software development
Such software development can be complex, especially in its early stages. Basically, there is often no clear way to turn an abstract idea into actual requirements.
So, let's examine all the key tech specifications that are usually implemented in medical imaging software apps:
Support for common medical image formats such as DICOM (including DICOM tags for metadata) and standards for storing, transmitting, and processing medical images (such as C-STORE, C-FIND, and C-MOVE).
Compatibility with various devices (CT, MRI, ultrasound, etc.).
Image processing can improve images by adjusting contrast brightness and applying filters. It can also segment them to highlight organs and tissues. Lastly, it can register them to compare scans over time.
2D and 3D visualization, including volume rendering (CT/MRI), support for iso-sections and reconstructions, and interactivity (e.g., rotation, zoom, and pan).
Data security, including HIPAA and GDPR compliance, support for TLS (for data transfer) and AES-256 (for image and metadata storage) encryption standards, as well as access control with role-based authorization and two-factor authentication.
PACS and EHR/EMR integration (e.g., via HL7/FHIR).
Annotation (adding labels, arrows, and text comments) and providing real-time collaboration tools.
PDF report generation and image export.
Scalability (including horizontal scaling via the cloud), multi-threading, and hardware acceleration.
WCAG 2.1 compliance and user interface customization.
Logging and monitoring events (including loading, processing, and exporting scans), auditing user access, tracking system performance, and setting up failure notifications.
Local deployment of software on physical servers (most likely, this will require ensuring compatibility with Linux and Windows OS).
Setting up regular data backups and automatic recovery after system failures.
Of course, this is just a basic list of specifications. In practice, your project team will expand and refine the list of features while specifying the tools and technologies for the project's unique needs.
Medical imaging software development cost
When it comes to the development cost of medical image analysis software it depends on its complexity and the technologies used. Without data and business needs—it's hard to define the precise price, but on average, basic DICOM (Digital Imaging and Communications in Medicine) typically ranges from $30K to $300K. A customized version of Basic DICOM may cost $30K to $50K. Advanced customizations could cost $70K to $150K.
Implementation costs differ based on the size of the practice:
Small practices typically cost $5K to $10K and take 1 to 2 weeks.
Medium facilities cost $20K to $50K and take 1 to 3 months.
Large enterprises may cost $100K to $200K and take 3 to 6 months.

Challenges in medical imaging software development
Let's examine the main challenges encountered when developing medical imaging software.
Regulatory compliance. Software handling sensitive data, like patient information, must comply with HIPAA, GDPR, FDA 21 CFR Part 11, and CE Marking regulations. Key security measures include code audits, RBAC, 2FA, and strong encryption (e.g., AES-256, TLS). To avoid fines, consult a local lawyer on medical standards.
Integration with existing systems. Integrating PACS, EHRs, and other systems requires DICOM, HL7, and FHIR support. Also, medical organizations have very different established IT infrastructures, which makes it hard to unify their software. If you create a universal solution, you must provide some middleware. It will help users adapt to various services and systems.
High performance and scalability.
Medical images, especially CT and MRI, are large. This can slow their processing and increase resource needs. In this regard, you may need to implement lossless compression mechanisms for images and multithreading and parallel data processing algorithms. By the way, a common fix is to move your software to a cloud solution designed for healthcare businesses.
The complexity of big data management.
Storing and processing massive data, like images and metadata, require a careful choice of databases and storage. In particular, this implies a preference for distributed databases and object storage. For even greater reliability, do not forget to provide backup and auto-recovery.
Risks associated with cyber attacks.
Cyber attacks that leak medical data are a serious problem for healthcare software. To solve it, you must implement constant monitoring. Also, set up regular security updates, including patches and OS updates. Finally, train your staff on social engineering. It can reduce the risks of phishing attacks. Providing a user-friendly interface. Interfaces for doctors and medical personnel should be user-friendly and intuitive, requiring minimal technical training to operate efficiently. To achieve this goal, you must test hi-fi prototypes on the real target audience and perform subsequent optimizations. Also, do not forget to ensure your interface is created under the WCAG 2.1 guidelines.
The future of medical imaging software
Medical imaging software development will advance by adopting the newest technologies, process optimization, and increased integration with other medical systems.
So, here are the core areas in which medical imaging software can be optimized:

Telehealth, simply put, is some type of delivery. It helps to provide health care services when patients and health professionals are separated by distance via remote technologies. Telehealth uses technologies for the exchange of information for the diagnosis and treatment of diseases and injuries for the patients. Live video conferencing, mobile health apps and remote patient monitoring (RPM) are examples of technologies used in telehealth.
It’s Healthtech time
Telehealth is improving the healthcare industry in many ways, the first of which is increasing its accessibility. Telehealth allows specialists to visit patients virtually from any place in the world by improving access as well as making a wider range of healthcare services available via telemedicine.
Today’s Telehealth environment consists of a global ecosystem of myriad digital solutions. There are two alarming end-users trends that you should pay attention to when considering Telehealth design and solutions.
What doctors struggle the most with
What people looking for when they choose the healthcare providers
Providing virtualized healthcare to any place in the world is one of the best-known applications of telehealth. But the medical industry is using it in several other ways, including:
Urgent help in distance. It can be a headache or sore throat. There are many medical complaints that aren’t life-threatening, but they need some professional attention. Virtual care services allow skilled health personnel to treat minor complaints, including providing appropriate prescriptions.
Stay in contact. Qualified medical personnel can use messages, phone and video calls to follow up the patients after they are discharged from the hospital. This way, improves worker productivity from not having to take time off and travel to appointments and ensures each patient understands the importance and carries out recovery and treatment plans. Also, telehealth platforms can automate much of the communication process, including sending reminders to the patients.
Updating online prescription. Telehealth provides the possibility to update online prescriptions even If you’ve been unable to get to your own doctor to refill a current prescription.
Monitoring of patients with chronic conditions. For these patients, it is one of the best benefits of telehealth. Virtual care helps those who have mobility issues, mental illness, and other conditions that may prevent them from going to in person medical appointments.
Facilitating care to rural areas. Telehealth is a great way to provide patients in places that are outside the current health delivery system with access to quality care. In the event of a medical emergency, telemedicine makes it possible to coordinate with specialists in other regions without wasting time to provide patients with effective treatment.
Increased patient satisfaction. In addition to referrals, many patients assess and choose healthcare providers through online reviews. As such, you must have positive reviews that will attract new patients. Telemedicine helps improve patient satisfaction scores by providing convenience of care and reducing wait time. The providers have the opportunity to offer remote services to the patients and make it convenient for them to receive medical attention. Also, this process reduces in-hospital visits.
All right, let’s move on to the design
Telehealth platforms require a unique approach to service design. As you can imagine, it isn’t the same way, say, for a food delivery service.
Telehealth is not about technology, it’s about people
That’s a good reminder that you need to create space for telehealth that provides human connections and assistance. The healthcare industry is unique and complex, and it can be challenging to set up. Establishing fundamental principles to guide telehealth design will help us keep sight of the user experience and user journey throughout different healthcare systems.
In this article, we’ll highlight the important and unique challenges in the design faced by digital health companies and startups.
Research. To begin, you need a shared understanding of how you usually provide face to face care. You will need a solid understanding of the patient’s journey through your service.
Construction. Based on our research findings, you need to discuss them with your client. There is the moment when you draft innovative solutions and delve into user journeys. We identify the most promising ideas based on jointly developed options. Service design can be quite abstract. The main idea is to find key service touchpoints.
Strategize and develop Next, it is necessary to work with your clients to co-create a product roadmap and business strategy. Together with medical professionals, you develop an extensive plan of the envisioned telehealth design, listing interactions between users, new processes, and workflows. Also, don’t forget to define the physical and digital things that will be used. By the end of this step, you’ve created visual content and material to start the development process.
Taking it live. From our experience, we recommend turning digital and physical artifacts into minimum viable products (MVP). MVP is essential to clinical trials. There is a product that has basic features and can be used to get feedback from the users.
After the main last modifications, it’s time for launch! At this stage, it’s important to provide testing to ensure that the envisioned workflow and interactions are happening as intended.
That’s it
To sum up, telemedicine is full of benefits for patients and healthcare providers. When people have had a taste of telehealth, they’re willing to continue using this convenient care option.
Telehealth’s future looks very bright, doesn’t it?
Also, it’s obvious to see continued strong growth and upgrade around devices, communication channels, telemedicine services, and telehealth platforms. Look for them to become increasingly user-friendly and convenient. As this happens, we can expect to see a resulting increase in users. After all, good design is the right way to improve engagement.
Designers will need to imagine themselves in both the patients’ and providers’ roles during the preparation for the start to create the design for telehealth. Every detail of a visit, from the method of scheduling appointments to the distribution of follow-up procedures, should be carefully planned to ensure the best outcomes and clear understanding.
We can expect to see digital pharmacies, virtual appointments, online triage tools, and remote monitoring gain in popularity. It may well become the new normal in healthcare.
Hey, are you here to find a solution for a consolidated and easy-to-access “home” for your business information, which is usually transferred from different places, often unrelated to each other? Then, you probably need to think about creating a digital space where it will be integrated, cleaned, structured, and stored accordingly, for further use in your regular business operations. But what is this space? Let’s find it out right now.
What Is Data Warehousing?
In a nutshell, it is a repository where your business data comes from disparate sources, where it is brought to the proper quality, and where it is stored, providing individuals with the appropriate rights with easy and fast access to it. Typically, such repositories serve as one of the central components in automated analytical solutions, but, as practice shows, the range of their application can be much wider.
Key Components of a Data Warehouse
In general, its main components are considered to be the following:
Sources, from which structured and unstructured information comes – these can be third-party databases, tables, systems, applications, etc.;
Data Extraction, Transformation, and Loading (ETL) tools, which define scenarios for extracting, transforming, and loading the information;
Data warehouse database, which is the main repository (usually in the form of a database management system, DBMS) with already prepared, i.e., cleaned and structured data, that can be used for analytics, reporting, and other business tasks without additional manipulation;
Metadata repository, which includes the permissible data types and the rules according to which this data will be used;
Query and reporting tools, which define algorithms for fast and unified access to data, as well as its analysis;
Data mart, a subset of the data warehouse that is used for individual business tasks (this can imply, for example, marketing data warehouse design) which formation occurs either directly through the collection from disparate sources or pre-preparing within a consolidated space.
Core Principles of Data Warehouse Design
Now, let's talk about the main data warehouse design principles:
A clear definition of business requirements and goals, as well as metrics that allow you to objectively assess the degree of their achievement;
Understanding how information is integrated from multiple sources and what should be the unified format after its transformation;
Choosing the right type of data modeling – these can be star schemas, snowflake schemas, fact tables, and so on;
Choosing the right methods and data warehouse software to ensure the quality and consistency of information, in particular, the methods of cleansing, validation, and supplementing of data;
Planning, scaling, and managing the performance through various methods of indexing, partitioning, compression, etc.;
Choosing the right tools for metadata management to simplify and improve access to the information;
Ensuring security and access based on policies and rules (usually, this is achieved through the implementation of advanced encryption algorithms, the introduction of access policies for different user groups, as well as providing reliable authentication and authorization methods);
Implementing end-to-end monitoring for ensuring data quality and security, performance of processes occurring within the data warehouse, and so on.
Steps in Data Warehouse Design
In this section, we invite you to consider the key steps leading to a successful and agile data warehouse design.
Requirement Gathering
According to the principles to design a data warehouse we defined above, the key to effective data warehouse design is to gather business requirements and clear business goals that it should fulfill. It is also important to identify the requirements for security, scalability, and performance of the repository.
Data Modeling
This is not yet a practical stage, but it still requires the participation of specialists – in particular, it implies the identification of entities, their attributes, as well as possible relationships between them. After this, the most suitable type of DBMS implementation needs to be selected – for example, in the form of tables, columns, indexing, etc. After this, you have to make sure that the selected type performs all the tasks assigned to it according to the predetermined requirements.
ETL Process Design
We have already explained above what the ETL process means, and this stage actually involves choosing the right tools and scenarios for their use.
In particular, you will need to define methods for extracting information from disparate sources (these can be database queries, API calls, file transfers, etc.), methods for bringing data to a single format and ensuring its proper quality (since you will most likely have to deal with big data, there may be many inconsistencies), methods for aggregating data to create complex information structures, automation methods for bulk loading of data (this can be full or incremental loading, and so on) with the usage of temporary storage areas, methods for detecting and eliminating data errors, as well as methods for checking data for completeness and accuracy.
Database Schema Design
There are several well-known data warehouse design patterns, such as:
Star, which has a fact table at its center and dimension tables associated with it around it;
Snowflake, which is a more complex Star and also implies additional dimension tables that surround each base dimension table;
Galaxy, which contains two fact tables and the dimension tables between them.
Data Integration
Now, you can start integrating the data using the previously defined ETL tools and technologies. At this step, you need to make sure that everything works as intended, and the data is transformed into the required unified format.
Data Storage Solutions
At this stage, you need to choose specific data storage solutions according to your requirements for the expected data volume, performance, scalability, and cost. Usually, the choice is made between relational databases, columnar databases, data lakes, and cloud data warehouse solutions.
Data Presentation Layer
Finally, to design data warehouse, you will need to understand what your data presentation layer will be – the layer at which end users will be able to seamlessly access the data and use it to solve specific business problems. This includes developing interfaces, dashboards, reports, and various data visualization tools.
