Device Story
Insight Enhanced™ DRF Digital Imaging System is an add-on imaging acquisition device for existing R&F fluoroscopic systems (GE Advantx, GE Legacy, GE P500, Shimadzu YSF300). It integrates dynamic flat-panel detectors (dFPD) (Vivix-D 1212G or 1717G) alongside or replacing the existing CMOS camera. The system captures high-definition fluoroscopic and spot images (up to 30 fps); processes images via an image processor PC; and displays them on monitors for clinical review. Operators use the system to enhance images to visualize diagnostic details. Images are stored locally or transmitted over a network for long-term storage/hardcopy printing. The device assists clinicians in diagnostic imaging by providing high-resolution visualization of anatomical structures, facilitating clinical decision-making through improved image clarity.
Clinical Evidence
No clinical data. Bench testing only. Phantom images were acquired using the subject device and compared to the predicate device on the same GE Legacy R&F system to assess image quality and radiation dose.

# 6. Difference Discussion
The dynamic flat-panel detectors Vivix-D1212G and Vivix-D 1717G have been added to the predicate system Insight Essentials in order to provide image acquisition support in addition to the existing CMOS camera.
# 7. Summary of the technological characteristics of the device compared to the predicate device
Both the subject device and the predicate device have the identical software program that provides a Graphical User Interface (GUI), image processing and patient workflow functions.
Two dFPD detectors have been added to the existing device Insight Essentials, to acquire fluoroscopic and spot images. The dFPDs are both manufactured by the same company Vieworks, use the same manufacturing technology but are of different sizes (12x12 inch and 17x17 inch). The subject device can now be configured with either a CMOS camera or one of the 2 dFPDs.
The VIVIX-D1212 dFPD has already been cleared by the FDA (K180473) for use on a mobile c arm. The Vivix-D 1717 uses the same architecture as the Vivix-D 1212 (K180473) and the only major difference is its larger size. A complete SSXI data report for the VIVIX-D 1717 is provided along with bench test data to establish substantial equivalency.
# 8. Description of non-clinical tests.
Bench testing was performed on the Vivix digital detectors used with the subject system Insight Enhanced, in order to assess substantial equivalence to the predicate device Insight Essentials. Phantom images were acquired with the subject device and compared to the predicate device, also installed on the same GE Legacy R&F system. These images and the doses used to acquire them were analyzed and compared. In conclusion, the tests obtained demonstrated substantial equivalence to the predicate device.
#### 9. Description of clinical tests.
No clinical data is necessary to evaluate safety or effectiveness for purposes of determining substantial equivalence of the proposed modification. Bench testing was performed to assess the device safety and effectiveness.
{7}------------------------------------------------
Image /page/7/Figure/0 description: The image shows three overlapping squares. The square on the left is dark blue, the square on the top right is orange, and the square in the middle where the other two overlap is light blue. The squares are made up of smaller squares arranged in a grid pattern.
# 10. Conclusion as to Substantial Equivalence.
The Insight Enhanced™ DRF Digital Imaging System, the subject device is substantially equivalent to the predicate (K191310). The intended use, the design principle, and the applicable standards for the subject device are identical to those of the predicate device. The performance test and non-clinical consideration result demonstrate that these differences do not raise any new questions of safety and effectiveness. Therefore, it is the sponsor's opinion that the subject device appears to be as safe and effective as the predicate device.

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.
