FDA-cleared profile
Siemens Medical Solutions U.S.A.
AI-Rad Companion Organs RT automatically contours predefined structures from DICOM images as an input to radiation-therapy planning workflows. VA50 added MR contouring with three T1 and six T2 target organs and updated CT contouring with 38 new organs; FDA materials limit MR validation to Siemens scanner data.
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.
Public materials reviewed for this batch do not establish the complete security posture for the exact release. Request architecture, data flow, identity, audit, encryption, retention, support-access, vulnerability-management, and incident-response evidence.
VA50 added MR contouring with three T1 and six T2 target organs and updated CT contouring with 38 new organs; FDA materials limit MR validation to Siemens scanner data. Procurement should map the installed build, modules, models, anatomies, inputs, and outputs to K232899 before acceptance.

Use a signed local test set spanning supported anatomies, scanners, protocols, unusual or postsurgical anatomy, and small or complex structures. Measure edit burden, rejection, downstream plan effects, and reviewer agreement rather than relying only on average overlap metrics.

Evidence
Metrics are shown only when they are tied to a source, endpoint, population, and tested product version.
Sensitivity is not an applicable primary endpoint for this radiation-planning software. Review structure-, model-, workflow-, and release-specific geometric, clinical-review, dosimetric, and edit-burden evidence instead.
Specificity is not an applicable primary endpoint for this radiation-planning software. Review structure-, model-, workflow-, and release-specific geometric, clinical-review, dosimetric, and edit-burden evidence instead.

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 release was found. Obtain a written quote separating license basis, sites or users, enabled modules or models, implementation, interfaces, compute, storage, training, support, upgrades, renewal, and exit costs.

Safety and lifecycle
Recall and adverse-event records are shown only after product matching. Adverse-event reports do not establish incidence or causality.
A zero-result exact-identifier search does not prove that no recall, correction, adverse-event report, or product-family safety signal exists. Maintain ongoing FDA and vendor surveillance.

Research record
This audit distinguishes completed source review from fields that have not yet been researched.
Recovered from the prior exact-submission extraction and normalized under the current provenance rules. Exact FDA decision materials, current product-family materials, directly relevant clinical literature, reimbursement context, and exact-identifier recall candidates were reviewed. Pricing, final security architecture, contracted services, enabled modules or models, interoperability, and local acceptance remain organization-specific evidence. Automated exact-name discovery found 8 PubMed and 0 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.
