FDA-cleared profile
Q Bio, Inc.
Constellation is intended for non-invasive labeling and calculation of quantitative measurements for anatomical regions using whole-body DICOM MR images gathered on a GE MR450W. It is intended for healthy adult patients and may be used as a clinical decision-support tool, but not in triage events, emergency medicine, or critical care; a clinician retains responsibility for diagnosis.
Clinical fit
Start with the authorized purpose, then verify how it fits your service line and reading workflow.
Regulatory identity
The FDA listing establishes the regulatory identity. It does not by itself establish local workflow fit, pricing, security, or performance in your environment.
Implementation
Use these fields to structure a vendor demo, security review, and implementation estimate.
This is a partial interface boundary described in the exact FDA package; current local compatibility, routing, identity, archive, and downtime behavior still require acceptance testing.
This is a partial release-level topology fact from the exact FDA package; current hosting, contracts, security, availability, and site configuration remain separate evidence.
Public materials reviewed for this exact release do not establish the complete security posture. Request data-flow, identity, audit, encryption, retention, remote-access, vulnerability-management, backup, and incident-response evidence.
This is buyer-facing monitoring guidance derived from the exact cleared scope; it is not a claim that the FDA package provides a live monitoring service.
Map installed model, build, options, population, anatomy, inputs, outputs, and enabled functions to K241280 before acceptance.
exact submission · checked 2026-09-04Later product-family features are not evidence that this cleared or authorized release includes them.
The exact FDA package describes internal-server hosting on off-the-shelf hardware; current infrastructure, contracts, security, availability, and site configuration remain unknown.
exact submission · checked 2026-09-04FDA-described topology does not establish current hosting contracts, security controls, uptime, or local qualification.
The exact FDA package describes whole-body DICOM MR input from a GE MR450W and quantified labels, measurements, whole-body visualization, and PDF reporting; verify the installed scanner, study identity, routing, report, and archive behavior.
exact submission · checked 2026-09-04Test representative identifiers, orientation, geometry, measurements, units, routing, failure handling, and round trips locally.
Use a signed local test set for the supported population and workflow. Include common and difficult cases, exclusions, acquisition variation, failed or low-quality inputs, reviewer overrides, and downstream effects. The exact indication is limited to healthy adults and excludes triage, emergency medicine, and critical care; Constellation is not intended as the sole source of diagnosis.

Model capital and recurring cost against net staff time after review, throughput, repeat imaging or rework, room time, consumables, infrastructure, training, service, downtime, upgrade, and replacement costs.

Evidence
Metrics are shown only when they are tied to a source, endpoint, population, and tested product version.
Sensitivity is not promoted as a product-wide endpoint. Compare only an exact endpoint, threshold, population, version, study design, and source if separately verified.
Specificity is not promoted as a product-wide endpoint. Compare only an exact endpoint, threshold, population, version, study design, and source if separately verified.
No contextualized exact-version metric has completed evidence review. Regulatory-document values, when available, are shown above with their limitations.
FDA decision evidence and product verification described in the exact submission or PMA decision record. · Whole body including lower-limb muscles, visceral and subcutaneous adipose tissue, kidneys, liver, spleen, lungs, and brain structures

FDA decision material is manufacturer-submitted regulatory evidence. It is not independent clinical validation unless the exact source expressly establishes that distinction; local technical, clinical, privacy, security, and workflow acceptance remains necessary.
Economics and lifecycle
These are common procurement questions; unknown values remain visible until a source supports them.
No public list price for the exact cleared or authorized configuration was found. Obtain a written quote separating license or hardware basis, implementation, interfaces, infrastructure, training, service, upgrades, renewal, consumables, and exit costs.
No exact-product reimbursement determination was promoted in this timeboxed review. Verify payer, site-of-service, coding, coverage, and local payment assumptions independently.
Safety and lifecycle
Recall and adverse-event records are shown only after product matching. Adverse-event reports do not establish incidence or causality.
Exact-identifier review does not prove absence of all product-family safety signals.

Research record
This audit distinguishes completed source review from fields that have not yet been researched.
Exact-submission ACR model-card fields were normalized under the current provenance rules; vendor and independent-study confirmation remain distinct. Scope was limited to exact FDA decision material and exact-submission recall disposition already present in the checked snapshot. Optional literature, vendor, pricing, and deployment research was not promoted. Automated exact-name discovery found 20 PubMed and 10 ClinicalTrials.gov candidate records. Candidates require human product and version matching; zero candidates is not evidence that no studies exist. Native FDA recall identifiers produced 0 postmarket candidate records; 0 have been reviewed (0 published, 0 rejected) and 0 remain unreviewed.
Candidate leads remain unpublished until a human confirms the exact product and tested version.
