| Device Description: | enCORE software is used on GE Lunar DXA bone densitometers.<br>Release 16 of the enCORE software (enCORE 16 or enCORE 16.xx)<br>includes some feature enhancements. The software will now expand<br>upon its previously cleared pediatric indication (K001812) by<br>providing a "Complete Pediatric" software that can measure the bone<br>mineral content (BMC), bone mineral density (BMD) and body<br>composition (lean body mass and fat mass) in patients from birth to<br>20 years of age. The software will also provide a comparison of<br>measured variables obtained by dual energy x-ray absorptiometry to<br>a database of reference values for patients 5-19 years of age. The<br>software will also expand its previously cleared orthopedic hip<br>indication (K972517) to include estimates of the BMD of the knee<br>before and after joint implant. |
| | The GE Lunar DXA bone densitometers measure the bone mineral<br>density (BMD), lean and fat tissue mass and calculate derivative<br>values of bone mineral content (BMC), area, soft tissue mass, regional<br>soft tissue mass, total soft tissue mass, fat free mass, regional/total<br>soft tissue mass ratio, % fat, region % fat, total body % fat, Android %<br>fat, Gynoid % fat, Android/Gynoid ratio (A/G ratio) and Body Mass<br>Index (BMI). |
| Intended Use: | The enCORE version 16 for GE Lunar DXA Bone Densitometers is<br>intended for medical purposes to measure bone density, bone<br>mineral content, and fat and lean tissue content by x-ray<br>transmission measurements through the bone and adjacent tissues. |
| Technology: | The enCORE version 16 Software Release for the GE Lunar DXA Bone<br>Densitometers employs the same fundamental scientific technology<br>as its predicate device, which is dual-energy x-ray absorptiometry<br>using a PC based image processing algorithm running on a Microsoft<br>Windows operating system. |
| | The enCORE version 16 Software Release for the GE Lunar DXA Bone<br>Densitometers has expanded the anatomical sites from the predicate<br>devices to now also include the knee for orthopedic examinations, pre<br>and post joint implant, with its optional orthopedic software. |
| | The enCORE version 16 Software Release for the GE Lunar DXA Bone<br>Densitometers has expanded the patient population from the<br>predicate devices for the complete pediatric software option to<br>accommodate those populations from birth to 20 years of age. |
| | The differences discussed in this section do not raise new issues of<br>safety and effectiveness. Verification and Validation testing<br>demonstrated that no adverse effects have been introduced by these<br>differences. |
| Determination of<br>Substantial<br>Equivalence: | Summary of Non-Clinical Tests: |
| | The enCORE version 16 Software Release for the GE Lunar DXA Bone<br>Densitometers and its applications comply with voluntary standards.<br>The following quality assurance measures were applied to the<br>development of the system: |
| | ■ Risk Analysis |
| | ■ Requirements Reviews |
| | ■ Design Reviews |
| | ■ Testing on unit level (Module verification) |
| | ■ Integration testing (System verification) |
| | ■ Performance testing (Verification) |
| | ■ Safety testing (Verification) |
| | ■ Simulated use testing (Validation) |
| | Summary of Clinical Tests: |
| | The subject of this premarket submission, enCORE version 16<br>Software Release for the GE Lunar DXA Bone Densitometers, did not<br>require clinical studies to support substantial equivalence. Bench<br>testing was performed to verify the effectiveness of the expanded<br>population range of the "Complete Pediatric" software application<br>from birth to 20 years as well as add the knee as an additional<br>anatomic site for the orthopedic software application. |
| Conclusion: | The enCORE version 16 Software Release for the GE Lunar DXA Bone<br>Densitometers expands upon its previously cleared pediatric<br>indication (K001812) by broadening the patient population from birth<br>to 20 years of age. The software will also expand its previously<br>cleared orthopedic hip indication (K972517) to include estimates of<br>the BMD of the knee before and after joint implant. It does not result<br>in any new potential safety risks, has the same technological<br>characteristics, and performs as well as the devices currently on the<br>market. |
| | After analyzing performance testing on the bench it is the conclusion<br>of GE Healthcare that the enCORE version 16 Software Release for the<br>GE Lunar DXA Bone Densitometers e is substantially equivalent to<br>other marketed devices with similar indications for use and meeting<br>the same standards. |

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.
