#### Device Description
IMAGEnet 6 Ophthalmic Data System is a Web application that allows management of patient information, exam information and image information. It is installed on a server PC and operated via a web browser of a client PC.
{4}------------------------------------------------
IMAGEnet 6 Ophthalmic Data System receives information from Topcon ophthalmological medical devices and saves the information including the patient information. The saved data can be displayed for diagnosis. In addition, it can save patient information, exam information, and image information as digital data to a database. These data can also be exported as digital data.
IMAGEnet 6 Ophthalmic Data System does not control or alter the functions or parameters of any medical device. IMAGEnet 6 Ophthalmic Data System is used in cooperation with the capture software designated for each capture device to retrieve image data such as an OCT image or a fundus image. IMAGEnet 6 Ophthalmic Data System receives, displays, and saves the image data captured with the capture software.
It also allows to send/receive patient information and image information, etc. to/from an external system via communication conforming to the DICOM standard.
# Intended Use / Indications for Use
The IMAGEnet 6 Ophthalmic Data System is a software program that is intended for use in the collection, storage and management of digital images, patient data, diagnostic data and clinical information from Topcon devices without controlling or altering the functions or parameters of any medical devices or through computerized networks. It is intended for processing and displaying ophthalmic images and optical coherence tomography data.
The IMAGEnet 6 Ophthalmic Data System uses the same algorithms and reference databases from the original data capture device as a quantitative tool for the comparison of posterior ocular measurements to a database of known normal subjects.
# Substantial Equivalence
Topcon's IMAGEnet 5 cleared in K132438 is the primary predicate for the IMAGEnet 6 Ophthalmic Data System. In addition to the functionality which is substantially equivalent to the IMAGEnet 5, IMAGEnet 6 Ophthalmic Data System has the OCT viewer function which retrieves saved OCT data (both fundus and tomographic images) and views the OCT images in both 2D and 3D formats. In order to demonstrate substantial equivalence of these features, the software from the Topcon 3D OCT-1 Maestro (K161509) is the secondary predicate device for IMAGEnet 6 Ophthalmic Data System.
{5}------------------------------------------------
The IMAGEnet 6 Ophthalmic Data System and the primary predicate device are both ophthalmic picture archiving and communications systems that collect, store, and manage digital images of the eye. The vast majority of product features are the same in the IMAGEnet 6 Ophthalmic Data System as in the IMAGEnet 5 including database, patient management, retrieval, display and operation, measurement, image tools, archive and backup, networking and security. image processing, import/export of images, and DICOM compliance, One difference between the IMAGEnet 6 Ophthalmic Data System and the primary predicate is that the IMAGEnet 6 Ophthalmic Data System can manage exam data including visual acuity and intraocular pressure data. This feature is not available in the IMAGEnet 5, however, this minor difference does not impact the safety or effectiveness of the device.
The IMAGEnet 6 Ophthalmic Data System has an additional feature which is substantially equivalent to the software of the secondary predicate device. The secondary predicate device is the Topcon 3D OCT-1 Maestro device which was cleared in K161509. The IMAGEnet 6 Ophthalmic Data System uses the same algorithms and reference databases as the cleared device which allows comparison of posterior ocular measurements to a database of known normal subjects. Both IMAGEnet 6 Ophthalmic Data System and cleared Topcon 3D OCT-1 Maestro device have similar software related functionality including: display, analysis, and access to the reference database for OCT data.
Therefore, the minor differences between the subject device and the predicate devices do not raise new questions of safety or effectiveness. The Topcon IMAGEnet 6 is as safe and effective as its predicate devices, and thus, may be considered substantially equivalent.
# Performance Data
Software verification and validation testing was conducted and documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." The software for this device was considered as a "moderate" level of concern, since a failure or latent flaw in the software could lead to an erroneous diagnosis or delay in delivery of appropriate medical care that would likely lead to a minor injury.
Additionally, the IMAGEnet 6 Ophthalmic Data System was tested to demonstrate that the measurement and analysis functions are equivalent to the predicate devices and been found equivalent to the predicate devices.
# Conclusions
{6}------------------------------------------------
Topcon's IMAGEnet 6 Ophthalmic Data System is as safe and effective as the previously cleared IMAGEnet 5 (K132438). In addition to the functionality which is substantially equivalent to the IMAGEnet 5, IMAGEnet 6 Ophthalmic Data System has the OCT viewer function which retrieves saved OCT data (both fundus and tomographic images) and views the OCT images in both 2D and 3D formats. In order to demonstrate substantial equivalence of these features, the software from the Topcon 3D OCT-1 Maestro (K161509) is a secondary predicate device for IMAGEnet 6. IMAGEnet 6 Ophthalmic Data System has the same intended use and similar indications for use, similar principles of operation, and similar technological characteristics as the previously cleared predicate devices and is therefore substantially equivalent.

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.
