### E.1.5 Substantial Equivalence
The RADIN Software is substantially equivalent, in the opinion of SOHARD AG, to Thinking Systems ThinkingNet (K010271, Class II).
#### E.1.6 Device Description
RADIN 3.0 is a system to distribute medical images and reports within and outside of health care environments. It is available as a stand-alone software package.
{1}------------------------------------------------
RADIN consists of the following set of software modules:
- t RADIN.online is the main component, its scalable server architecture provides high availability of medical images
- . RADIN.web provides standardized internet technology for web-based image communication
- RADIN.archive enhances RADIN.online with long term archiving on media (e.g. harddisk, jukebox)
RADIN offers three types of clients:
- RADIN.Classic Client provides the basic viewing and workflow features, e.g. . support of CR, CT, MR and NM modalities, support of greyscale, color and multiframe images.
- . RADIN.Expert Client additionally offers gamma adjustment, display of scoutlines and image export.
- . RADIN.Expert dual monitor Client supports dual monitor operation
RADIN requires standard PC-Hardware, recommendations are made within the labeling.
#### E.1.7 Intended Use
RADIN 3.0 is a system to distribute medical images and reports within and outside of health care environments.
The RADIN Server receives image data in DICOM format via the hospital network. This provides universal connections to archives, modalities and workstations. The modalities that are supported by RADIN are listed in the DICOM Conformance Statement [1].
For data transfer to clients you have to activate strong SSL data encryption to make the transfer secure.
Data that are stored on the RADIN server can be accessed simultaneously by many viewing stations within a healthcare enterprise or from elsewhere outside. The image data transfer is done in DICOM format via the Intranet or the Internet, for example to stations located in a doctor's office, throughout hospitals or a physician's home.
Integration with other hospital information systems (HIS, RIS, CIS) is possible via a special OEM interface.
Images can be viewed directly within a web browser (Internet Explorer). The system offers simple functions for image manipulation and measurements. Reports can be viewed together with the images on one page.
RADIN can support physicians and/or their medical staff with the diagnosis. In that case the user is responsible for all suitable hardware being used in proper working conditions. The final decision regarding diagnoses, however, lies with the doctors and/or their medical staff in their very own responsibility.
{2}------------------------------------------------
Lossy compressed mammographic images and digitized film screen images must not be reviewed for primary image interpretations. Mammographic images may only be interpreted using an FDA approved monitor that offers at least 5 Mpixel resolution and meets other technical specifications reviewed and accepted by FDA (concerning only the USA).
RADIN offers an archiving option for long-term storage of image data. Only the data consistency on archive media is guaranteed, the system provider has to take own appropriate means (e.g. redundancy) for safety against data loss caused by media destruction. Without the archiving option, the RADIN System features no components for long-term data archiving. Additional archiving on film or in digital form is therefore necessary.
RADIN provides three types of clients:
RADIN.Classic for basic functionality RADIN.Expert for full functionality RADIN.Expert Dual Monitor with RADIN.Expert functionality and support of two monitors
All text and messages displayed in the image viewer can be viewed in either: German English French Spanish Italian Portuguese
The Online Help for the image viewer is available in German and English. The text of the administration pages and the Online Help of the administration pages are available in English only.
To guarantee flawless operation of the RADIN system, no additional 30 party software may be installed on RADIN server. Furthermore, no part of the RADIN product may be manipulated in any way.
If the system is configured to use only patient ID for matching of patient data, the system provider has to make sure that each patient ID is unique for the whole system. Therefore, all interfaces that can deliver images into the system have to be considered especially interfaces to external institutions.
### E.1.8 Software Development
SOHARD AG certifies, that the RADIN software is designed, developed, tested and validated according to written procedures identify individuals within the organization responsible for developing and approving product specifications, coding and testing, validation testing and field maintenance.
All employees receive the appropriate quality system training.

### E.1.10Safety and Effectiveness
#### E.1.10.1 General Safety and Effectiveness Concerns
RADIN is a medical device that is to be used by trained health care professionals who are responsible for the correct and accurate use of medical images e.g. as a means for providing diagnosis.
The device labeling contains instructions for use and the intended use/indications for use. Warnings, faults etc are explained in the users manual.
lmages that are compressed are properly identified in the image information as being compressed as specified by the DICOM standard. This compression identification remains with the image for the entire life of the image.
#### E.1.10.2 Validation and Effectiveness
The RADIN risk analysis has been performed to identify all potential safety or health hazards during system operation. The hazards are controlled by a risk management plan, including hazard analysis, verification and validation tests (according to our software development process) and evaluations by hospitals.
{7}------------------------------------------------
According to our risk analysis and risk management there are no software components within the RADIN Software, whose failure or latent design flaw would be expected to result in death or injury to a patient.
Requirement tracing covering specification, design, implementation and verification/validation ensures the fulfillment of all phase requirements, EHR and DMR ensures direct access to all documents.
Integration test plan defines full testing at integration and system testing level. According to this test plan integration and system testing including full testing of hazard mitigation has been performed.
Decision Reviews at the conclusion of each software development phase ensure the fulfillment of the phase results and the validity of the Intended Use and the risk analysis.
Testing is an integral part of our Software Design Process.
#### Substantial Equivalence E.1.10.3
Any differences between the RADIN Software and the substantially equivalent device have no significant influence on safety and effectiveness.
#### E.1.10.4 Technological characteristics
RADIN is a stand-alone software package used on general purpose hardware, as long as the minimum hardware requirements specified in the manuals are met.
It is based upon standard Microsoft™ technology.
The device does not contact the patient, nor does it control any life sustaining devices.
A physician, providing ample opportunity for competent human intervention interprets images and information delivered by RADIN.
#### E.1.10.5 Conclusion
SOHARD
We believe, that the 510(k) premarket notification contains adequate information and data to enable FDA to determine substantial equivalence to the predicate device.
RADIN has been and will be manufactured in accordance with the mandatory and voluntary standards listed in this submission.

Two short videos show you everything — or skip straight to the written tutorial if you'd rather read. You can reopen this any time from the Tutorial button in the top bar.
Part 1 — Search, results, and everyday workflows 16 min
Part 2 — Embeddings: the galaxy map 3 min
1. Search: exact and fuzzy
Type a phrase like "coronary artery calcification" into the search box. You get two kinds of results. Exact results match the literal phrase — prefix searches work ("coronary artery calcificati") but suffix searches do not. Fuzzy results match on the meaning and intent of your phrase rather than the exact words, and are sorted by relevance score. Hover over the Exact or Fuzzy badge on any row to see exactly why it matched.
Use the checkboxes above the results to narrow: SaMD keeps only software-only devices, AI / ML keeps only devices with AI.
Exact vs. fuzzy search: what's the difference?
Exact matches on the literal phrase (prefix search works, suffix does not). Fuzzy matches on the meaning and intent of the phrase rather than the exact words. Hover over the badge on any row to see why it matched.
You search "coronary artery calcification" and want only software devices with AI. What two filters do you apply?
Narrow by SaMD (software-only devices), then narrow by AI/ML (devices with AI).
2. The results table
Scroll right in the results table. The intended use is extracted for you — no need to open the PDF. The device story gives a high-level snapshot of what the device does and how it's used. The AI Performance sub-table shows each output name, acceptance criteria, observed values, and development/test dataset descriptions — the same format Innolitics uses for regulatory strategy outputs, and the fastest high-level fingerprint of an AI device. It is AI-generated but has been very reliable in practice.
Where do you find a device's intended use without opening the PDF?
Scroll right in the search results table. The intended use column is extracted for you; no need to dig into the 510(k) summary PDF.
What does the AI Performance sub-table show, and why is it useful?
Output name, acceptance criteria, observed values, development dataset description, and test dataset description. It's the same format we use for regulatory strategy output and Fast 510(k) input, and the fastest high-level fingerprint of an AI device. AI-generated but reliable in practice.
3. Judging fuzzy relevance
Fuzzy results trail off in relevance as you scroll. Use three signals to decide how far down to go: the fuzzy badge explanations, the intended use column, and whether your target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, you're past the relevant zone. A top hit with a low score (~0.4) and a stretched explanation is a hint the closest predicates are far away — the project may be headed for De Novo. Note the fuzzy search is a pattern match: it doesn't handle negation ("not") well, and hardware devices can appear — filter by SaMD/AI ML to cut them.
How do you judge how far down fuzzy search results to go?
Use the relevancy signals: the fuzzy badge explanations, the intended use column, and whether the target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, results are trailing off in relevancy.
4. Device detail page: chat and citations
Click a device name to open its detail page: device facts on the left, a chat window on the right. Ask something like "Describe the training data". The answer carries little citation bubbles — click one to jump to the highlighted passage in the source PDF, so you can verify every AI answer against the document. There's also a Download PDF button for sharing.
How do you verify an AI chat answer on the device detail page?
Click the citation bubbles to jump to the relevant highlight in the source document.
Reading rule for every project: how many summaries do you read in full?
At least the three most relevant 510(k) or De Novo summaries, in full. After that, use targeted chat questions to confirm your memory quickly. The tool supports this professional habit — it doesn't replace it.
5. Side-by-side comparison
Select multiple rows in the results table (aim for under ~10), then open the PDF Viewer tab. Ask one question — it goes to all selected devices in parallel, each with citations. This is the fastest way to compare and contrast devices: training data, PCCP scope, how they handled adding new scanners, and so on.
What does the side-by-side PDF viewer mode do?
Select multiple devices, open the PDF viewer tab, and ask one question (e.g., "Describe the training data"). It queries all selected devices simultaneously with citations, so you can compare and contrast quickly.
6. Collections
With rows selected, go to the Collections tab and create a labeled collection (e.g., "Cobb Angle Project"). Reload that selection any time — before a client call, pull up the collection and ask questions across all of its devices at once.
How do you save a set of selected devices for later use?
Select the rows, go to the Collections tab, and create a labeled collection (e.g., "Cobb Angle Project"). You can reload the selection anytime and carry it into the PDF viewer and other tabs that support selections.
7. Product codes and the regulations tree
Click a product code in the results to jump to it in the regulations tree — identification text, sibling product codes, and devices you can open in a PDF viewer on the right. Click a regulation number to see its identification, special controls, and related product codes. You can also search by product code or regulation number at the top of the tree. Always read the special controls if any exist for your device — it broadens your search and sharpens pre-kickoff research.
What can you do from the regulations tree view?
Browse product codes and regulation numbers, read the identification text and special controls, browse sibling product codes, open device PDFs on the right, and search by product code or regulation number at the top of the tree.
8. Chart view
Click Show Chart and segment by regulation number (or product code) to see which regulations dominate your result set. Clicking a regulation takes you into the regulations tree. Great for spotting that most matches are, say, hardware laparoscopic devices — a cue to go back and filter.
How do you see which regulations dominate a search result set?
Click "Show Chart" and segment by Regulation Number. Clicking a regulation takes you to the regulations tree.
9. The predicate graph
Open the Predicates tab for a family-tree view of predicate relationships. Click a node to trace its parents and children; selections from search carry over pre-selected. Commonly predicated devices are worth reading — a lot of people predicated them for a reason. The visual lineage is also handy on client calls, e.g. to show how a predicate family evolved and justify why your predicate still holds.
In the predicate graph, why are commonly predicated devices worth reading?
A lot of people predicated them for a reason. Clicking a node traces parents and children, and selections from search carry over pre-selected.
10. Embeddings: the galaxy map
The Embeddings tab plots every matching document in a 2-D "galaxy map" where semantically similar devices cluster together. Hover or click clusters to explore, and let AI label the clusters for you. Embeddings beat product codes for grouping: two devices can carry different product codes (LLZ vs. QIH) yet do the same thing — the embedding captures the meaning of the intended use and device story. This is also exactly how retrieval-augmented generation (RAG) works under the hood, and it makes a great visual on client calls.
Try it yourself
Head to the search page and work through a few of these AI/ML fuzzy searches to build intuition: perivascular fat on CT · aortic valve calcification opportunistic screening on noncontrast CT · breast cancer prediction on digital pathology slides · autism detection · gestational age prediction · a hearing aid that can also detect a pulse · foundation model based analysis of ECG · large language models · penetration test. Watch how the relevance scores, intended use, and AI Performance tables tell you when results stop being meaningful.
