Indications for Use
TBS iNsight is indicated as an adjunct to BMD and other clinical factors, for the assessment of bone health and the management of primary and secondary osteoporosis. Primary osteoporosis can occur in both sexes with aging, and in females due to the menopause and associated estrogen deficiency. Secondary osteoporosis occurs as a result of an underlying disease or condition, which alters bone metabolism leading to a net loss of bone and degradation of bone quality, for example, diabetes, hyperparathyroidism, chronic kidney disease and rheumatological conditions.
Device Story
TBS iNsight (V4) is a software application that processes raw DXA images of the AP lumbar spine to calculate Trabecular Bone Score (TBS), a metric reflecting bone microarchitecture. It functions as a complement to standard DXA BMD analysis and clinical risk factors. The device uses an Adapted Experimental Variogram (modified fractal-like approach) to measure spatial variation in image texture. Unlike its predecessor, V4 directly measures tissue thickness from DXA data rather than estimating it via BMI. The system architecture consists of a client-side 'TBS Agent' on DXA scanners and a centralized server for result management and DICOM/PACS communication. Used in hospitals and radiology clinics by physicians, radiologists, and DXA technicians, the output provides TBS scores, T-scores, Z-scores, and FRAX-adjusted fracture risk probabilities. These outputs assist clinicians in diagnosing osteoporosis, assessing fracture risk, and monitoring treatment efficacy. The software does not provide automated diagnoses or treatment recommendations; final clinical decisions remain the responsibility of the healthcare professional.
Clinical Evidence
Evidence includes ex vivo and in vivo studies. Ex vivo validation using 30 human cadaver vertebrae showed strong correlations between TBS V4 and microCT bone microarchitecture parameters. Agreement studies (15 cadaver vertebrae) showed excellent agreement with the predicate (r > 0.99). Reproducibility was confirmed in 132 participants across four DXA systems, meeting ISCD precision standards. Fracture risk assessment performance was validated using data from >17,000 individuals across 14 international cohorts, demonstrating statistical equivalence to the predicate in TBS-adjusted FRAX and BMD T-score outputs.
Technological Characteristics
Software-based bone densitometry analysis. Inputs: raw DXA images. Processing: Adapted Experimental Variogram (modified fractal-like approach) for texture analysis. Direct tissue thickness measurement (7-30 cm range). Connectivity: Client-server architecture (TBS Agent on DXA, centralized server), DICOM/PACS integration. Cybersecurity: Data encryption (at rest/transit), role-based access control. Compatible with GE and Hologic DXA systems.
Indications for Use
Indicated for men and women for bone health assessment and fracture risk management. TBS iNsight computes Trabecular Bone Score (TBS) from AP lumbar spine DXA images as a complement to DXA analysis and clinical examination. Optional 10-year fracture risk assessment (hip and major osteoporotic) via FRAX, validated for Caucasian and Asian men and post-menopausal women aged 40-90. Not validated for individuals under 20 years old.

# Indications for Use
510(k) Number (if known) K243218
Device Name TBS iNsight (v4)
#### Indications for Use (Describe)
TBS iNsight is a software provided for use as a complement to both DXA analysis and clinical examination. It computes the antero-posterior spine DXA examination file and calculates a score (Trabecular Bone Score - TBS) that is compared to those of the age matched controls. The TBS is derived from the texture of the DXA image and has been shown to be related to bone microarchitecture.
TBS iNsight provides as an option an assessment of 10-year fracture risk. It provides an estimate of 10-year probability of hip fracture and 10-year probability of a major osteoporotic fracture (clinical spine, forearm, hip or shoulder fracture). This estimate is based on the WHO's FRAX® Fracture Risk Assessment Tool, after adjustment for the TBS. The tool has been validated for Caucasian and Asian men and post-menopausal women between 40 and 90 years old.
TBS provides information independent of BMD value: it is used as a complement to the data obtained from the DXA analysis and the clinical examination (questioning by the clinician about patient history, bioassay of bone resorption markers...).
The results can be used by a physician in conjunction with other clinical risk factors as an aid in the diagnosis of osteoporosis and other medical conditions leading to altered trabecular bone microarchitecture, and ultimately in the assessment of fracture risk.
The TBS score can assist the health care professional in monitoring the effect of treatments on patients across time. Overall fracture risk will depend on many additional factors that should be considered before making diagnostic or therapeutic recommendations. The software does not disease or recommend treatment regimens. Only the health care professional can make these judgments.

## Device Description Summary
TBS iNsight is a software application provided for use as a complement to bone mineral density (BMD) acquired from dual energy X-ray absorptiometry (DXA) and other clinical risk factors for osteoporosis and fragility fracture. It calculates a score (Trabecular Bone Score - TBS) derived from the texture of the DXA image of the anterior-posterior (AP) lumbar spine and has been shown to be related to bone microarchitecture. The method analyzes X-ray based images acquired by DXA imaging systems and produces the TBS based on the computation of an Adapted Experimental Variogram (modified fractallike approach). This variogram is used to measure the degree of spatial variation between pairs of data points in a spatial dimension of a region of a digital image.
The absolute TBS values for the same equivalent tissue thickness vary slightly between GE and Hologic systems. Additionally, within each system, variability in TBS values can be observed across different scan modes. To address these differences, corrections are applied that are both device-specific and mode-specific. For instance, TBS is corrected differently for GE and Hologic systems to account for inherent differences in tissue thickness assessment. Furthermore, corrections are also tailored separately for each scan mode within the same system, ensuring that TBS measurements remain consistent and reliable regardless of the scan mode used. These device-specific and mode-specific corrections are necessitated by differences in the dynamic range of tissue thickness measurements between GE and Hologic devices. The variations arise due to differences in the methodologies used to assess tissue thickness. To harmonize these discrepancies and ensure measurement accuracy, correction fits derived from ex-vivo data are applied individually to each device and scan mode. This approach ensures the accuracy and consistency of TBS measurements across all configurations.
The device is intended to be used for bone health assessment in medical facilities employing one or more DXA system(s) to which the subject device is connected. These facilities are usually hospitals, clinics, healthcare centers, radiology practices and medical imaging centers. The software is designed to be used by qualified clinical professionals (including physicians, radiologists and DXA technicians) and the physicians are solely responsible for making all final patient management decisions.
## Intended Use
TBS iNsight is indicated as an adjunct to BMD and other clinical factors, for the assessment of bone health and the management of primary and secondary osteoporosis. Primary osteoporosis can occur in both sexes with aging, and in females due to the menopause and associated estrogen deficiency. Secondary osteoporosis occurs as a result of an underlying disease or condition, which alters bone metabolism leading to a net loss of bone and degradation of bone quality, for example, diabetes, hyperparathyroidism, chronic kidney disease and rheumatological conditions.

## Technological Comparison
The subject device, TBS iNsight V4, has been designed to maintain identical core functionalities as its predicate, specifically in the computation of Trabecular Bone Score (TBS) from DXA (Dual-energy X-ray Absorptiometry) image texture and the provision of complementary DXA analysis. TBS iNsight V4 and the predicate compute TBS from DXA image textures and provide complementary DXA analysis, ensuring continuity in the primary operational utility of the technology.
Differences:
- Algorithm for Tissue Thickness: Unlike the predicate device which uses BMI to estimate tissue thickness in its TBS computation algorithm, the subject device directly measures tissue thickness (TT) using the DXA system. This direct measurement potentially increases the accuracy of TBS calculations.
- System Architecture: The system architecture of the subject device represents an evolution from the standalone software model used in the predicate. The subject device includes a two-component system comprising a TBS Agent (client) installed on each DXA device and a centralized server that manages results and facilitates DICOM communication with PACS. This advancement supports enhanced scalability and integration within clinical settings.
- Data Security: TBS iNsight V4 introduces robust encryption protocols by incorporating encryption or role-based access control, aligning the new device with current best practices in data security.

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.
