Developing medical-imaging AI applications has unique challenges. These challenges are difficult for startups to address with small in-house teams or generalist development firms. Here are some of the unique challenges companies in this space will need to overcome:
Challenge: AI Performance Validation
FDA requires clinical validation of most AI models. Inexperienced teams can lead to costly delays. Common problems include:
Insufficiently diverse training or testing data
Inappropriate data management or controls
Insufficiently rigorous reference standard
Inappropriate validation study design
To ensure your models get past FDA review, it is critical to have a team that understands FDA’s expectations around training data coverage, data controls and AI lifecycle processes.
FDA is placing an increasing focus on the AI development lifecycle
within their regulatory review.
How Innolitics Meets this Challenge
We have 11 engineers (including 3 PhDs) with deep image-processing expertise in traditional image processing and AI-based methods.
Our team of six FDA regulatory consultants have helped over 100 companies FDA clear medical device software. We have a deep understanding of the relevant FDA guidance and regulations.
What our Clients Say
During a presubmission meeting, the FDA acknowledged that Innolitics were “extremely advanced” in their understanding of the regulations. The FDA essentially concurred with all of Innolitics’ advice, demonstrating a deep understanding of the regulations, even in the face of ambiguous topics such as CADe vs non-CADe. They expertly, and politely, navigated the FDA call with our best interests in mind while fostering a collaborative exchange with the agency.
Ilya Pyatnitskiy, MD
Cofounder of AUMI AI
I worked with Innolitics to develop an application that analyzes MR images of our geometric distortion phantoms. It was a quite challenging image-processing project. In the end my company and Innolitics team were able to meet the challenge and built a quality web UI and a robust analysis pipeline. Innolitics seems like a company that is run by engineers who care about doing quality work.

Technical Product Manager - Therapeutic Physics at Mirion Medical
The work conducted by Innolitics to complete a complex software port of a core module of our clinical product was outstanding. The clinical product must by cleared by the FDA, and as such, we needed the highest quality workmanship, and close collaboration with a dispersed team. Innolitics performed exceedingly well in gathering requirements, researching, developing and implementing a design, and providing test modules and documentation. Their team’s understanding of medical imaging analysis software, and FDA quality processes, was key to the success of the project.
This article outlines the process of developing an AI/ML algorithm from scratch and getting it FDA cleared. It covers the four phases of the process (Explore, Develop, Validate, and Document) and discusses the costs, time, and data requirements involved. It also provides advice on regulatory strategy, data annotation, and algorithm prototyping. If you’re interested in developing a medical device involving AI/ML.
The article outlines a method for documenting AI/ML algorithms for FDA pre-submissions. It emphasizes clear algorithm descriptions to avoid delays. Key steps include visual runtime descriptions, dataset analysis, non-ML testing, annotation details, AI/ML test plans, and performance metrics. It stresses reducing annotation costs and leveraging existing data while advising comprehensive documentation for effective FDA evaluation.
Challenge: Design Documentation for FDA Submissions
When you submit your 510(k) or De Novo application to FDA, you’ll need to provide comprehensive documentation of your product's development process, risk management activities, software architecture, and verification and validation testing.
It is not uncommon for companies to take 9 - 12 months just producing the documentation! This problem is so common that we offer our Fast 510(k) service to companies who are done with development but who didn’t produce the necessary design documentation. This service typically takes 3 months and costs $200k or more. For example, we’ve had to take over projects developed by over-seas teams who were unable to comply with this rigorous documentation.
It is much more efficient to pay more up front for a development team that can provide all of the necessary design documentation.

How Innolitics Meets this Challenge
Our Medtech OS platform is purpose built for medical device software submissions. Our engineers are trained on its use and it provides all of the documentation required for FDA submissions.
We’ve helped over 100 companies FDA clear their medical device software and have a thorough understanding of the relevant guidance and standards.
What our Clients Say
Thanks to Innolitics, we were able to complete the software documentation for our 510(k) in just 4 months. They flew onsite to absorb how our software worked and provided detailed guidance. Without Medtech OS, training, and support, I can easily imagine the process taking 12 months. Our engineering team was able to focus on feature development instead of being bogged down with documentation. We tried three different consultants before finding Innolitics. None of them could deliver. Innolitics took the reins and made it happen. I don’t see how we would have completed our 510(k) without them.
VP of Systems R&D
IVD Startup
I engaged Innolitics to develop a companion app for a COVID testing kit sold directly to users. The app’s purpose was to walk people at home through using the test kit. Innolitics was a pleasure to work with. They worked systematically, beginning with a planning phase to collect and clarify our user needs and requirements and ending with thorough V&V and documentation. I’m proud of the app we built together and would certainly work with them again.
This checklist is meant to assist in the review of a 510(k) submission. It is a version of the checklist we use internally at Innolitics when we’re reviewing 510(k) submissions for our clients. The checklist applies to any SaMD 510(k) submissions made for medical devices.
Integrating within the clinical workflow is critical for success. Doing so requires an understanding of DICOM, HL7, and FHIR. It also requires a real-world understanding of hospital IT environments. Although acceptance of cloud-based deployments is growing, many institutions still require on-site deployments.
Furthermore, performance is critical. Radiologists are busy, highly paid professionals with low tolerance for waiting. They will not wait for large images to load. Solving these performance issues is challenging given the size and quantity of image sets (MRIs and CTs).
How Innolitics Meets this Challenge
We have over 5 years of experience deploying and maintaining AI-enabled radiology software.
We are DICOM experts (e.g., our DICOM Standard Browser is used by over 10,000 people each month).
What our Clients Say
We engaged Innolitics as a software partner for our AI/ML-enabled radiology application. Their knowledge of AI/ML deployments, DICOM, and FDA regulations added a lot of value on a tight pre-seed budget. We’d definitely recommend them for their niche expertise in medical-device AI/ML.
Raj Shah, MD, MBA
Co-Founder of GuidewireRX
Innolitics’s engineers seamlessly integrate with our existing team. They’ve consistently produced high quality work while helping us solve technical problems in the medical imaging space. In particular, they spearheaded development of a large module that extends our existing product suite. This module has since been cleared by the FDA and is live at hospitals around the world. Their work on the module involved software development, researching various image processing algorithms, analysis of these algorithms against real-world data, and writing detailed technical documentation of the system that justified its approach to the FDA.
Medical device design begins with design inputs. The FDA says developing your design inputs is “the single most important design control activity,” yet writing good design inputs is difficult. This article presents Innolitics’ answers questions our clients frequently ask us about design inputs and analyzes a number of poorly written example requirements.

FAQ
Can you help us collect and annotate data for our model?
Yes, since we’ve been working in the radiology space for over a
decade, we have a broad network of data providers and clinicians. In
most cases, we can help procure data and clinical specialists to help
annotate the data.
Do you work on non-imaging AI applications?
Yes! Although our deepest expertise is in the imaging domain, we also
have experience with IVDs and other signal-processing applications.
Let’s talk and we can explore if we’re a good fit for your needs.
How much does your typical project cost?
End-to-end projects can vary quite a bit depending on several
factors:
Whether the core algorithms or models have been proven
The size and complexity of the user interface (if any)
The number of platforms that are needed
The risk-classification of the device (higher-risk devices require
more documentation and testing)
The performance or hardware constraints
The number of integrations with external systems
And many other factors.
Our project-based engagements typically start at $50k.
Full end-to-end projects tend to start around $200k.
Do you ever work on a fixed-price basis?
We do not work on a fixed-price basis for large projects, but in some
cases we may begin projects with a fixed-price scoping phase or a small
fixed-price initial engagement.
For our project-based engagements and end-to-end engagements we
provide detailed cost and timeline estimates. We refine and periodically
update these estimates throughout the project.
Can you provide examples of past projects similar to our product?
Yes! Please review our
case studies for a sampling of our past projects. If you don’t see
anything relevant, please reach out as only a small number of our
projects have case studies.
How do you handle project management and communication during the development process?
For staff-augmentation projects we assume you will be managing our
resources along with the rest of your team.
For our project-based and end-to-end engagements we provide project
management support. Here are a few of the highlights:
We set up preferred communication channels during kickoff (often
Slack or Microsoft Teams)
We follow an agile process with one- or two-week sprints
During these meetings we demo our work and plan the next sprint
We provide periodic budget and timeline estimate updates
What experience does your team have with FDA regulatory submissions for medical devices?

the world when it comes to medical device AI software.
Does your team do firmware development?
Several engineers on our team have experience with firmware
development, however, we typically are not the best fit for
firmware-heavy projects. We excel on Software in a Medical Device (SiMD)
projects that involve a lot of application-level coding, such as web,
mobile, or desktop UIs, cloud deployments, image processing, etc.
Can your team help design our user interface?
Yes. Typically we will develop an initial set of UI Mockups in Figma
and will then have a Medical Device UI/UX designers polish and further
refine the slides.
What if your engineers don’t know a core technology that we use?
Good engineers can usually become proficient using new databases,
frameworks, or even programming languages pretty quickly. Tools like
GitHub Co-Pilot and ChatGPT have made it learning new technologies even
easier.
If this is a major concern, we may cover the cost of training
engineers on new technologies.
Can your engineers work within our QMS?
Yes! We can work within your QMS or within ours. We are happy to sign
a quality agreement to coordinate quality activities. We can also train
our engineers within your QMS. This often makes sense for Staff
Augmentation engagements.
Can you help us set up a Quality Management System (QMS)?
Yes. We can get you set up on our Medtech OS platform. This is the
platform we use for our QMS. You can read more about
Medtech OS here.
Can you run our QMS?
Sorry, although we’re often asked to do this, we do not currently
help companies run their QMS, however, we can provide guidance and
support. We do have several partners whom we can recommend who can help
you run your QMS.
