Image quality and validation of marketing claims
Indications for Use
SmartCT assists physicians during vascular and non-vascular procedures, with diagnosis, treatment planning, interventional procedures and treatment follow-up by creating 3D views from sets of 2D images created during rotational acquisitions. SmartCT provides high-speed and high-resolution 3D visualizations of vasculature, hemorrhages, soft tissue and bone structures. SmartCT provides live image guidance for navigating endovascular devices through vascular structures anywhere in the body. SmartCT helps to assess anatomical information intra-procedurally, such as the estimate of a vessel or lesion size, diameter or volume, and anatomical distances between relevant structures. SmartCT is intended to be used for human patients that have been elected for the procedures as described in these Indications for Use.
Device Story
SmartCT is 3D visualization/analysis software for interventional X-ray systems; transforms 2D rotational X-ray acquisitions into 3D volumes. Operates via analytical, filtered back-projection algorithms; includes filters for artifact reduction (metal, motion, scatter). Provides 3D roadmap, vessel analysis, and manual measurement tools for lesions/vessels. Used in interventional suites by physicians/technicians for intra-procedural guidance; supports navigation of endovascular devices. Output visualized on interventional workspot; assists in identifying pathologies and planning interventions. Does not provide HU-calibrated quantitative output; requires confirmation by 2D X-ray. Benefits include improved anatomical assessment and navigation during neuro/vascular procedures.
Clinical Evidence
No prospective clinical investigation conducted. Evidence relies on bench testing (image quality, geometric accuracy, artifact reduction) and a comparative reader assessment using retrospective clinical datasets from adult neuro-interventional procedures (aneurysm embolization, thrombectomy, etc.). Reader assessment validated image quality and marketing claims via Likert-scale evaluation by board-certified physicians.
Technological Characteristics
Software-based 3D reconstruction; analytical filtered back-projection algorithm. Supports circular, helical, and dual-phase rotational trajectories. Includes artifact reduction filters (metal, motion, scatter). DICOM compliant. Cybersecurity per ANSI UL 2900-1/2-1.

510(k) Summary
# Technological characteristics:
SmartCT R3.0 (L 10) has similar technological characteristics compared to the predicate device. Neither the subject device nor the predicate device displays HU values or provides HU-calibrated quantitative radiodensity output; accordingly, diagnostic HU-scale conformance is not a technological feature of the devices' intended clinical function.
Similar features are used in the predicate and subject device, with exception of the following major modifications implemented in SmartCT R3.0 (L 10):
# Improved image quality for neuro CBCT imaging (NeuroHQ)
SmartCT R3.0 (L 10) provides support for updated neuro 3D acquisition protocols, which are added to the Azurion interventional X-ray system. The 3D acquisition protocols are:
- Updated: Circular CBCT scan, using a circular trajectory;
- Added: Helical CBCT scan, using a dual axis rotational trajectory; and
- Added: Dual Phase CBCT scan, using two subsequent circular CBCT scans for neuro within the same acquisition protocol.
SmartCT R3.0 (L 10) introduces an updated 3D reconstruction algorithm for the updated 3D acquisition protocols. It includes filters to reduce cone beam, bone beam, system vibration, ring and table scattering artifacts. Next to this it offers the following optional secondary 3D reconstruction filters to reduce typical neuro procedure artifacts on:
- Metallic objects (e.g., endovascular devices such as coils)
- Patient head motion (to compensate for patient motion during the CBCT acquisition)
# Extension of interventional X-ray System compatibility
Compared to SmartCT R1.0, SmartCT R3.0 (L 10) extends compatibility with the latest available Interventional X-ray Systems:
- Azurion R2.2, Azurion R3.0 and Azurion R3.1
- Updated acquisition protocols are introduced with their corresponding calibration protocols. By installing the NeuroHQ acquisition protocols and performing the corresponding calibrations.
# Reconstruction algorithm
For NeuroHQ imaging, the updated 3D reconstruction algorithm implemented in SmartCT R3.0 (L 10) is based on an analytical, filtered back-projection-type algorithm. The method is physics-based and models X-ray attenuation and acquisition geometry to reconstruct volumetric images from rotational projection

data, supporting both circular and helical acquisition trajectories. The reconstruction process consists of deterministic steps including preprocessing of projection data, frequency-domain filtering, and back-projection into a 3D volume. In addition to the primary 3D reconstruction, the SmartCT R3.0 (L 10) provides optional secondary reconstruction workflows for image quality improvement (e.g., reduction of artifacts from metallic objects and patient head motion), which may involve multiple reconstruction passes using repeated forward- and back-projection operations.
Warning: Images created by the viewing application are artificially reconstructed images and the selected viewing settings may affect the image visualization. Diagnosis or treatment cannot be solely based on these images. All findings, decisions, and diagnoses must be confirmed by the use of conventional (2D) X-ray imaging.
The differences between SmartCT R3.0 (L 10) and the predicate device do not raise any new questions regarding safety or effectiveness. Based on the information provided, SmartCT R3.0 (L 10) is considered substantially equivalent to the currently marketed and predicate device SmartCT R1.0 in terms of fundamental scientific technology.

510(k) Summary
# Summary of Clinical Performance Data:
No prospective clinical investigation involving the testing of new patients was conducted for SmartCT R3.0 (L 10). Substantial equivalence to the currently marketed predicate device, SmartCT R1.0, was demonstrated based on indications for use, technological characteristics, non-clinical performance testing, and safety and effectiveness considerations.
Previously acquired clinical image data from adult patients undergoing representative neuro-interventional procedures were used in a comparative reader assessment and were relied upon to support the determination of substantial equivalence for applicable device claims and features. The retrospectively collected datasets originated from clinical sites in the United States, Asia, and Europe and included procedures such as cerebral aneurysm embolization, mechanical thrombectomy for vessel occlusions, trans-arterial embolization, and carotid artery stenting. As the evaluation was performed using previously acquired clinical image data rather than prospective patient testing, assessment of device-related adverse events or complications was not applicable.
# Substantial Equivalence Conclusion:
SmartCT R3.0 (L 10) is substantially equivalent to the currently marketed predicate device SmartCT R1.0 (K201583) in terms of indications for use, technological characteristics and safety and effectiveness.
Additionally, substantial equivalence was demonstrated by non-clinical performance tests provided in this 510(k) premarket notification. These tests demonstrate that SmartCT R3.0 (L 10) complies with the requirements specified in the international and FDA-recognized consensus standards and is as safe and effective as its predicate device without raising any new safety and/or effectiveness concerns.

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.
