| Device description: | CT TrueView is a software medical device with the following characteristics:<br>The proposed CT TrueView is considered an accessory to the currently marketed Allura Xper FD series X-ray System (Philips Medical Systems Nederland B.V., K141979). It operates on the currently marketed Interventional Workspot (Philips Medical Systems Nederland B.V., K121296) software hosting platform. The proposed CT TrueView assists physicians during cardio-vascular interventions by providing a 3D model of the coronary vessel tree. The 3D model is created from a pre-acquired 3D CT dataset segmented by the user. The proposed CT TrueView supports the physician navigating a catheter or guide wire through the coronary arteries by providing a composite image that combines a 2D X-ray exposure with a CT based 3D visualization of the heart and/or coronaries. The proposed CT TrueView provides a range of viewing angles that result in an unobstructed and minimally foreshortened projection of a specific segment and/or bifurcation. The selected viewing angles are programmed automatically on the connected Allura Xper FD series X-ray system. The proposed CT TrueView includes measurement tools to estimate the length and diameter of a segment of the 3D model and to estimate the bifurcation angle of a bifurcated segment. The proposed CT TrueView provides a CTO Navigator feature that allows the user to combine a 2D X-ray image with the 3D model of the heart and/or coronaries in one composite image. | |
| Indications for Use: | CT TrueView assists physicians during cardio-vascular interventions when analyzing 2D images by segmenting a previously acquired 3D CT to create a 3D model of the coronary vessel tree.<br>CT TrueView supports the physician navigating a catheter or guide wire through the coronary arteries by providing a composite image that combines a 2D X-ray exposure image with a CT based 3D visualization of the heart and/or coronaries. | |
{4}------------------------------------------------
CT TrueView is suitable for use with the adult human population.
{5}------------------------------------------------
Technological At a high level, the subject and predicate device are based on the following same technological elements: characteristics:
- Both are intended to be used in combination with the currently marketed . Allura Xper FD series X-ray System (Philips Medical Systems Nederland B.V., K141979). They both have X-ray system integration, can be controlled from the table side of the Allura Xper FD series X-ray system and get input data from the aforementioned Allura Xper FD series X-ray system.
- Both use a segmentation technique to create a 3D model of the coronary ● tree.
- Both use a cardiac modeling technique to obtain a still 3D model of the heart and /or coronary arteries.
- Both can display data that indicates the lesion length and diameter present in the segment without foreshortening.
- Both allow the physician to determine an optimal projection to visualize a specific vessel segment or bifurcation.
- Both offer visualization tools that allow the physician to manipulate and view the 3D model in different ways.
The following technological differences exist between the subject and predicate device:
- CT TrueView has automatic segmentation instead of semi-automatic . segmentation. The user can correct the segmentation results.
- o CT TrueView not only uses 2D images generated by the Allura Xper FD series X-ray system, but also uses previously acquired 3D CT data.
- CT TrueView allows the physician to assess and determine the angle of ● bifurcating vessel branches.
- CT TrueView offers curved reformat and cross sections views of the 3D model.
- CT Trueview contains an optional CTO Navigator image fusion functionality that provides a static composite image that combines a 2D Xray angiographic image with the CT based 3D model of the heart and/or coronaries. This static composite reference image assists the physician in navigating the catheter or guide wire through the coronary arteries.
As these differences/additional technological characteristics are considered low risk (only providing further support to the clinicians in performing interventions) and the functionalities were verified and validated with equivalent methods, these differences do not raise new questions on safety or effectiveness.
Therefore, CT TrueView is substantially equivalent to the currently marketed predicate device Allura 3D-CA Release 1 in terms of technological characteristics.
{6}------------------------------------------------
Summary of Nonclinical Performance Data:
Non-clinical performance testing has been performed on CT TrueView and demonstrates compliance with the following International and FDA-recognized consensus standards and FDA guidance document:
- IEC 62304 Medical device software - Software life cycle processes (Ed. 1.0. 2006).
- IEC 62366-1 Medical devices Part 1: Application of usability engineering ● to medical devices (Ed. 1.0, 2015-02),
- ISO 14971 Medical devices Application of risk management to medical ● devices (Ed. 2.0, 2007),
- NEMA PS 3.1-3.20 Digital Imaging and Communications in Medicine (DICOM) Set (2011), and
- . Guidance for Industry and FDA Staff – Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices" (issued May 11, 2005, document number 337).
Software verification testing included the following activities:
- Verification of the functional, non-functional and user interface ● requirements as well as the identified hazard mitigations. Result: all verification tests were executed successfully, showing that the requirements are met and hazard mitigations are implemented correctly.
- Verification of the accuracy of the measurement tool. Result: The accuracy ● of the measurement tool is in line with its specification.
Software validation testing included the following activities:
- Validation of the intended use and commercial claims. This has been performed via in-house validation. Results show that CT TrueView can be used as defined in the Intended Use and the commercial claims.
- Usability validation. The results of the usability analysis indicate that the ● usability of CT TrueView is acceptable.
- Algorithm validation, consisting of two studies: ●
- Validating the orientation mismatch between the 3D model of an object and the modeled object. This has been done with 3 different phantoms representing a coronary vessel tree, a vessel with an occlusion and a vessel with stenosis.
- Validating the performance of the TrueView tool in determining an optimal projection to visualize a specific vessel segment or bifurcation without foreshortening or overlapping branches.
The results of the two studies show that the algorithms provide the user with correct information required to support the clinical procedure within the scope of the intended use of CT TrueView.
All of these tests were used to support substantial equivalence of the subject device. The test results in this 510(k) premarket notification demonstrate that CT TrueView:
- complies with the aforementioned international and FDA-recognized ● consensus standards and FDA guidance document, and
- meets the acceptance criteria and is adequate for its intended use. ●

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.
