The IRm is a mobile x-ray system to be used for 2D planar and fluoroscopic and 3D imaging for adult and pediatric patients. It is intended to be used where 2D and 3D information of anatomic structures such as bony anatomy and soft tissue and objects with high X-ray attenuation such as (metallic) implants is required. The IRm provides an interface that can be used by system integrators for integration of the IRm with image guidance systems such as surgical navigation systems.
Device Story
Mobile ImagingRing System (IRm/Loop-X) is a robotic, digital X-ray system for 2D fluoroscopy and 3D Cone-Beam Computed Tomography (CBCT). Input: X-ray projections acquired via a ring-gantry with independently movable arms (X-ray source/collimator and flat-panel detector). Output: 2D/3D images for diagnostic/interventional procedures. Used in sterile/non-sterile areas (OR, clinic) by physicians (surgeons, radiologists). Integrates with surgical navigation/therapy systems (linear accelerators, surgical robots) via DICOM or proprietary network interfaces. Internal/external cameras track surgical instruments/pointers in the imaging coordinate system. Output assists clinicians in intraoperative guidance, patient positioning, and therapy control, potentially improving clinical outcomes through precise visualization of anatomy and implants.

### Device Description:
The Mobile ImagingRing System (IRm, "Loop-X" or "Loop-X mobile Imaging Robot") is a robotic, digital X-ray system which supports both 2D planar and fluoroscopic X-ray and 3D Cone-Beam Computed Tomography (CBCT) image acquisition and reconstruction of a patient's anatomical regions of interest (ROI).
The design of the Mobile ImagingRing is based on a ring-gantry ("ring") with two arms mounted: the first arm on gantry carries a monoblock X-ray source and a collimator, the second holds a flat-panel detector. The two arms are independently moveable to accommodate individual patient setups and off-center imaging of regions of interest.
The ImagingRing m / Loop-X Imaging Robot is intended for mobile use on patients in general and interventional radiology, in sterile and non-sterile areas. The system can be used for diagnostic and interventional purposes by volumetric or planar X-ray imaging and enables image-quided maneuvers and operations in medical fields such as general surgery. traumatology, orthopedics, neurology or radiotherapy. The system is designed for flexible examinations and treatments with patients lying, sitting or standing, with and without contrast agent. It can also be combined with therapy devices such as linear accelerators, particle beam delivery systems or other irradiation devices with active sources and patient positioning systems in Image Guided Radiation Therapy, Intraoperative Radiation Therapy, Brachytherapy or surqical navigation and assistance systems as well as in combination with surgical robots in lmage Guided Surgery, in which the image data provided by the ImagingRing IRm / Loop-X m can be used directly with patient in situ to control the respective therapy maneuvers. Using additional equipment, such as external tracking cameras or the built-in optical cameras, the position of objects such as tracked surgical instruments or pointer tools, for example, can also be determined in the imaging coordinate system. This position data, in combination with the patient's pre- and intra-interventional imaging data, can be used in guided or navigated workflows. The internal cameras of the IRm can also be used to capture pictures and film sequences of the medical procedures.
#### Intended Use / Indications for Use:
The intended use / indications for use statement has been specified as follows:
"The IRm is a mobile x-ray system to be used for 2D planar and fluoroscopic and 3D imaging for adult and pediatric patients. It is intended to be used where 2D and 3D information of anatomic structures such as bony anatomy and soft tissue and objects with high X-ray attenuation such as (metallic) implants is required. The IRm provides an interface that can be used by system integrators for integration of the IRm with image guidance systems such as surgical navigation systems."

information systems (HIS) facilitates import and export of DICOM files from the subject device to an external DICOM server as well as the import of patient data (using DICOM Modality Worklist) from an external DICOM server to the subject device.
- In parallel, a proprietary navigation network-interface for communication of the subject . device with external systems (such as surgery planning and support systems or radiation therapy control systems in brachytherapy) is provided. External optical tracking systems can be used to track the position of the IRm's gantry based on passive reflectors (markers) that are attached to it. The IRm's imaging coordinate system can then be registered with an external reference coordinate system and based on this the external system can, for example, visualize tracked surgical instruments on the images provided by the IRm.

Image /page/10/Picture/2 description: The image contains a logo for a company called medPhoton. The logo features the letters 'm' and 'p' in a stylized, cursive font, with the 'p' resembling the Greek letter phi (Φ). The letters are in blue, and the word "medPhoton" is written in gray below the symbol.
Like the listed predicate device, the medPhoton Mobile ImagingRing System (IRm) is a mobile x-ray system intended to be used for 2D fluoroscopic and 3D imaging (adult and pediatric patients). Both devices are intended to be used where 2D and 3D information of anatomic structures such as bony anatomy and objects with high X-ray attenuation such as (metallic) implants is required. Also, both devices are prepared for (equipped with respective interfaces) integration with image guidance systems, such as surgical navigation systems.
The technological characteristics (materials, energy sources, other features) of the subject device are not significantly different - i.e. can be considered the same - as those of the predicate device.
The device design of the subject device and the predicate device (gantry vs. C-arm) is significantly different, however, this difference raises no new questions of safety and effectiveness. The existing questions of safety and effectiveness have been addressed and answered in the submission of the reference device (K191267) which has the same design as the subject device. The Mobile ImagingRing System does not introduce new potential hazards or safety risks.
Since the subject device can therefore be considered to be as safe and effective as the predicate device and since they also have the same intended use, medPhoton is certain that the devices are substantially equivalent.
## Summary of performance testing:
#### Bench Testing:
Non-clinical bench performance testing has been conducted to further support substantial equivalence of the subject device and the predicate device. The main aspects in determining substantial equivalence are the intended use of the devices, their technological characteristics as well as safety and effectiveness of the devices.
A system level validation has been conducted, which provides evidence that the Mobile ImagingRing System (IRm, Loop-X Mobile Imaging Robot, Loop-X) meets all customer and system requirements and is able to perform according to its intended use.
Clinical use of the device in general and its clinical imaging performance in particular have been tested using phantoms and cadavers. Those clinical imaging tests were conducted with the subject device as well as the predicate device. Results suggest that the subject device performs at least as good as the predicate device (in terms of resolution capabilities) or better (in terms of a larger dynamic range) and therefore support the demonstration of substantial equivalence.
Although safety and effectiveness of the subject device's design have been demonstrated for a

Image /page/11/Picture/2 description: The image shows the logo for medPhoton. The logo features the letters 'm' and 'p' in a stylized, connected design. The 'm' is rendered in a flowing, cursive style, while the 'p' is represented by the Greek letter Phi, which is in blue. Below the symbol, the word 'medPhoton' is written in a sans-serif font, with 'med' in gray and 'Photon' in a slightly darker shade of gray.
reference device (with the same design), additional bench testing pertaining to a variety of different mechanical characteristics of the device design were conducted. Results demonstrate the safety and effectiveness of the subject device in terms of its design.
Voluntary consensus standards applied during design and development include but are not limited to IEC 60601-1, IEC 60601-1-2, IEC 60601-1-3, IEC 60601-2-43, IEC 60601-2-54, IEC 62304, IEC 62366 and ISO 14971. Standard compliance has been demonstrated in a variety of tests conducted internally (by medPhoton) and by an external accredited testing laboratory.
In summary, the results of all non-clinical bench performance tests support substantial equivalence of the subject device and the predicate device and demonstrate safety and effectiveness of the subject device.
#### Animal Testing:
medPhoton GmbH did not perform any animal testing for the Mobile ImagingRing System.
#### Clinical Testing:
medPhoton GmbH did not perform any clinical testing for the Mobile ImagingRing System.
Conclusion: medPhoton GmbH believes that the Mobile ImagingRing System is substantially equivalent to the currently legally marketed devices. The Mobile ImagingRing System does not introduce new indications for use, has the same technological characteristics and does not introduce new potential hazards or safety risks.

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.
