VeriSuite is an active therapeutic medical device for verification of the patient position and calculation of a correction vector for the treatment of tumors during a radiation therapy with photons, electrons (from a linear accelerator) or particles (protons, heavy ions). The VeriSuite system calculates digitally reconstructed radiographs (DRRs) based on a high-resolution CT data set for a treatment position. With these DRRs and Xray images acquired during the performance of the position verification procedure a correction vector for the patient position can be calculated. The VeriSuite® system with fluoroscopy extension provides the possibility to a medical user to observe the position of the patient and the treatment area during the treatment, mainly the movements of the patient caused by breathing. This information can be used to interrupt the treatment. An authorized person must evaluate the correctness of the calculation and approve the result for further usage. The system shall only be used after correct installation in appropriate treatment rooms by trained personnel. Legal regulations especially requlation for the operation of X-ray devices must be regarded. VeriSuite must not be used for diagnostic purposes.
Device Story
VeriSuite is an image processing system for radiotherapy patient positioning. Inputs include real-time stereoscopic X-ray images and DRRs derived from patient CT scans and treatment planning data. The system calculates a correction vector to align patient position with the treatment plan. The fluoroscopy extension allows clinicians to monitor patient/treatment area movement, specifically respiratory motion, to manually interrupt treatment if necessary. Used in treatment rooms by trained personnel; requires authorized user evaluation and approval of calculated corrections. Benefits include improved accuracy of radiation delivery to tumors and real-time monitoring of patient movement.
Clinical Evidence
Bench testing only. Non-clinical verification and validation software tests were conducted to confirm the system meets intended use and safety requirements.
Technological Characteristics
System includes VeriSuite software, Ralco 302 collimators, Sedecal SHF 835 X-ray generator, Varian A277/A272 X-ray tubes, and Varian 4030E flat panel digital imagers. Operates via stereoscopic X-ray imaging and DRR calculation. Complies with IEC 61217 (coordinates/movements), ISO 14971 (risk management), and IEC 62304 (software lifecycle).
Indications for Use
Indicated for patient position verification and correction during radiotherapy treatment with external beams or charged particles. Used for patients undergoing radiation therapy for tumors. Not for diagnostic use.

#### F. Description
VeriSuite is an image processing system for verification and correction of the patient position during a radiation therapy treatment. The verification or correction is performed by a comparison of X-ray images that are acquired during the treatment with DRRs (digital reconstructed radiographs) calculated from a CT image series of the patient and information from the radiation therapy planning. The correction can also be based on fiducial, radio-opaque markers that are implanted in the patient.
With the fluoroscopy extension it is possible to observe the position of the patient and the treatment area during the treatment. Mainly the movements of the patient caused by breathing are in the focus. This information can be used to interrupt the treatment by the user.
VeriSuite is a system of devices consisting of the VeriSuite software and a number of hardware devices:

#### G. Intended Use
VeriSuite is an active therapeutic medical device for verification of the patient position and calculation of a correction vector for the treatment of tumors during a radiation therapy with photons, electrons (from a linear accelerator) or particles (protons, heavy ions).
The VeriSuite system calculates digitally reconstructed radiographs (DRRs) based on a high-resolution CT data set for a treatment position. With these DRRs and Xray images acquired during the performance of the position verification procedure a correction vector for the patient position can be calculated.
The VeriSuite® system with fluoroscopy extension provides the possibility to a medical user to observe the position of the patient and the treatment area during the treatment, mainly the movements of the patient caused by breathing. This information can be used to interrupt the treatment.
An authorized person must evaluate the correctness of the calculation and approve the result for further usage. The system shall only be used after correct installation in appropriate treatment rooms by trained personnel. Legal regulations especially requlation for the operation of X-ray devices must be regarded.
VeriSuite must not be used for diagnostic purposes.
#### H. Technological Comparison to Predicate Devices
The changed device VeriSuite 1.8 (build number B641.4, subject of this submission) is substantially equivalent to the predicate device VeriSuite 1.8 (K092653) except the fluoroscopy extension.
{3}------------------------------------------------
Image /page/3/Picture/1 description: This image shows handwritten text on a white background. The text includes "K133914" at the top, followed by "Page 4 of 4" in a cursive style. Additionally, there is a printed line of text at the bottom left that reads "Page 9 of 44". The handwriting appears to be done with a dark ink pen.
The fluoroscopy extension of VeriSuite is substantially equivalent to the fluoroscopy functionality of the predicate device EXACTRAC 5.5 / ExacTrac X-RAY 6D (K072506) in terms of intended use and technology.
In contrast to EXACTRAC 5.5, VeriSuite does not support optical prepositioning and internal respiratory gating signal display. Because of the reproducibility of the patient preposition due to the fixation of the patient, optical prepositioning is not required in the VeriSuite environment. Respiratory gating can be displayed using external devices.
Minor differences exist in the hardware used in terms of resolution of the flat panels, x-ray image and pixel size, which are higher for VeriSuite.
Refer to section XII for a detailed predicate device comparison.
#### l. Non-clinical Performance Data
Non-clinical verification and validation software tests were conducted to confirm that VeriSuite 1.8 with fluoroscopy meets its intended use and is safe and effective. See section XVI.I for details.
#### J. Conclusion
Based on the information provided in this Premarket Notification MedCom concludes that VeriSuite 1.8 with fluoroscopy extension is as safe and effective and substantially equivalent to the predicate devices described herein.

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.
