Indications for Use
The separately-licensed CT Colonography option is intended for closely examining the lumen of the colon using features such as auto-segmentation, axial imaging, multi-planar reformatting, fly-through, simultaneous display of prone and supine images, and transparent wall view.
Device Story
Vitrea CT Colon Analysis is radiological image processing software used by radiologists, clinicians, or technologists to visualize and analyze colon CT scans. It inputs DICOM CT data and provides tools including auto-segmentation, multi-planar reformatting, 3D volume rendering, and endoluminal fly-through. A key feature is Electronic Bowel Cleansing, which electronically removes residual fecal material tagged with a contrast agent to improve visualization of the colon wall. The software operates on the Vitrea platform; it does not provide automated diagnosis but assists the physician in identifying polyps, masses, and lesions. Output is displayed on a workstation for clinical review, supporting decision-making by providing clearer views of potential pathologies. It benefits patients by facilitating more thorough colon examinations, particularly when full bowel evacuation is incomplete.
Clinical Evidence
No clinical studies were required. Safety and effectiveness were demonstrated through non-clinical bench testing, including software verification, validation, phantom testing, and simulated usability testing by experienced professionals. Performance metrics for the Electronic Bowel Cleansing feature were evaluated using real patient data and phantoms to ensure accuracy in polyp diameter measurement and segmentation.
Technological Characteristics
Radiological image processing software; DICOM-compliant; operates on the Vitrea platform. Features include auto-segmentation, 3D volume rendering, and Electronic Bowel Cleansing (tagging/subtraction). Complies with DICOM, IEC 62304 (software life cycle), and ISO 14971 (risk management) standards. Deployment is via the Vitrea platform.
Indications for Use
Indicated for adult patients with suspected colon pathologies (e.g., polyps, masses, lesions) to aid radiologists, clinicians, or technologists in screening and assessment.

Image /page/5/Picture/0 description: The image shows the word "VITAL" in black, with the "i" having a dot above it. Below the word "VITAL" is the phrase "A Toshiba Medical Systems Group Company" in red. The text is centered and the font is sans-serif.
## Intended for Disease / Condition / Patient Population:
The software provides trained Radiologists, Clinicians or Technologist with a robust dedicated suite of software tools to aid in the creation of evidence to support these physicians with their screening and assessment of adult patients with suspected colon pathologies (i.e. suspicious polyps, masses, and lesions).
## Rationale for Additions and Enhancements to CT Colonography Software:
Vitrea users, require an intuitive, accurate, and efficient application to review, investigate, and problem solve their colonography exams in order to provide information for the referring clinicians. Many patients are unable to complete full evacuation of fecal material and residual liquids in the colon, which can obscure potential lesions and pathology. Vital customers have repeatedly requested to have functionality to electronically remove this residual material from the colon in order to fully evaluate the colon for any abnormalities. When viewing the colon in either 2D or 3D it is very important to see all aspects of the colon, so Vital is introducing "Bowel Cleansing" as a means to remove any residual materials that may inhibit a reader from fully visualizing all aspects of the colon interior. Vital customers will now be able to electronically remove any residual fecal material that has been tagged with a tagging agent.

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).

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.
