### Device Description
The modified DRX Plus 3543C is a scintillator-photodetector device (Solid State X-ray Imager) utilizing an amorphous silicon flat panel image sensor. The modified detector is redesigned with the intent to reduce weight and increase durability, while utilizing a non-glass substrate material and cesium iodide scintillator. The modified detector, like the predicate is designed to interact with Carestream's DRX-1 System (K090318).
The modified DRX Plus 3543C Detector, like the predicate, creates a digital image from the x-rays incident on the input surface during an x-ray exposure. The flat panel imager absorbs incident x-rays and converts the energy into visible light photons. These light photons are converted into electrical charge and stored in structures called "pixels." The digital value in each pixel of the image is directly related to the intensity of the incident x-ray flux at that particular location on the surface of the detector. Image acquisition software is used to correct the digital image for defective pixels and lines on the detector, perform gain and offset correction and generate sub-sampled preview images
The modified and predicate are essentially the same as they are both digital x-ray flat panel scintillatorphotodetector devices (Solid State X-ray Imagers) utilizing an amorphous silicon flat panel image sensor. The predicate and modified are both DRX Plus 3543 flat panel detectors, the difference is that the modified device utilizes a cesium iodide (Csi) scintillator, whereas the predicate utilizes gadolinium oxysulfide (GOS). The modified device official product name is marketed as "Lux 35 Detector." Both flat panels operate primarily in a wireless state, using a battery for power and allows wireless communication for control and data transmission. This eliminates the need for cables that can hinder efficient workflow. The detectors have the ability to communicate via a wired ("tethered") connection to the console, if desired
#### Technological Characteristics
The modified detector is substantially equivalent to the predicate device currently cleared on the market (K150766) and uses the same fundamental scientific technology as the predicate device. The detectors are both digital x-ray flat panel scintillator-photodetector devices (Solid State X-ray Imager) utilizing an amorphous silicon flat panel image sensor. The predicate and modified are both DRX Plus 3543 flat panel detectors, the main difference is that the modified device utilizes a cesium iodide (Csi) scintillator and non-glass substrate whereas the predicate utilizes gadolinium oxysulfide (GOS) and a glass substrate. The modified device official product name is marketed as Lux 35 Detector.
Both flat panels operate primarily in a wireless state, using a battery for power and allows wireless communication for control and data transmission. This eliminates the need for cables that can hinder efficient workflow. The detectors have the ability to communicate via a wired ("tethered") connection to the console, if desired. The modified detector is designed to interact with Carestream's existing acquisition software that resides on the legally marketed Carestream DRX-1 System (K090318). The predicate device (DRX Plus 3543) has clearance with DRX-1 under K150766. Additionally, the DRX-1 System has clearance for the following Carestream detectors:
- K130464 (DRX 2530C)
- . K183425 (DRX Plus 2530 Detector)
- K150766 (DRX 3543 Plus Detectors) .
{5}------------------------------------------------
Carestream has obtained previous detector clearances for use with DRX-1, as listed above. This submission is for the clearance of the modified digital flat panel detector only.
After images are captured with the digital flat panel detector and can be communicated to the DRX-1 System console. The DRX-1 System contains Image Eclipse Processing Software II to allow rendering of the images. The image is processed and transformed into data for viewing and then put into DICOM format for output. Image Eclipse Processing Software II has been cleared for use (K180809) with previous Carestream DRX Plus 2530C under K183425.
The image acquisition software corrects the digital image for defective pixels and lines on the detector. perform gain and offset correction, and generate sub-sampled preview images. The image acquisition software that resides on the DRX-1 System console will be replaced with Image View Software. The ImageView Software has obtained several FDA clearances for use with Carestream Digital Radiography Systems used with the Carestream flat panels:
- 트 K163203 - DRX Evolution System with Image View Software
- . K191205 - DRX-Mobile Revolution System with Image View Software
- . K201373 - DRX-Compass

### Summary of Non-Clinical Testing
Clinical testing was not required to establish substantial equivalence. Bench testing was sufficient to assess the device safety and effectiveness. The performance of the modified device DRX Plus 3543C (Lux 35) detector was evaluated in non-clinical (bench) testing using a Phantom Image Study. A technical analysis (non-diagnostic) of image quality attributes such as detail, sharpness, noise and appearance of artifacts were compared for each image.
Greater than 84% of all responses were rated 0 or higher in favor of the modified DRX Plus 3543C panel. All ratings for the attributes (detail contrast, sharpness and noise) were significantly greater than 0 indicating that the modified DRX Plus 3543C images were equivalent to just noticeably better than the predicate images.

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.
