FDA-cleared profile
Siemens Medical Solutions USA, Inc
AI-Rad Companion Organs RT automatically contours predefined structures from DICOM images as an input to radiation-therapy planning workflows. VA40 added analysis of 29 head-and-neck structures while retaining locked CT models and mandatory review in a treatment-planning or interactive-contouring application.
Clinical details
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.
VA40 added analysis of 29 head-and-neck structures while retaining locked CT models and mandatory review in a treatment-planning or interactive-contouring application. Procurement should map the installed build, modules, models, anatomies, inputs, and outputs to K221305 before acceptance.
exact submission · checked 2026-09-03Later product-family features are not evidence that an earlier cleared release includes them.
DICOM CT or MR input, DICOM RTSTRUCT output, configurable DICOM-node transfer, organ-template configuration, and a web-based confirmation interface.
exact submission · checked 2026-09-03Test representative imports, exports, identifiers, orientation, geometry, structure names, units, failure handling, and round trips in the local environment.
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.
product family · checked 2026-09-03Define stop-use, escalation, rollback, and revalidation triggers before production use.
Model total annual and per-plan cost against hands-on and elapsed time after review, correction, failed transfers, rework, support, upgrades, downtime, and any effect on plan quality or throughput.
product family · checked 2026-09-03Vendor time-saving results are scenario inputs, not guaranteed local savings.
Monitor by exact software and model version, anatomy, structure, scanner and protocol, patient position, contrast, unusual or postsurgical anatomy, reviewer role, edit time, rejected outputs, DICOM-transfer failures, downstream plan effects, incidents, recalls, and updates. Revalidate after material workflow or model changes.

Evidence
Metrics are shown only when they are tied to a source, endpoint, population, and tested product version. Candidate literature without exact product and version linkage is not shown as product evidence.
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.

Manufacturer evidence submitted for substantial equivalence. VA40 added analysis of 29 head-and-neck structures while retaining locked CT models and mandatory review in a treatment-planning or interactive-contouring application.
PMID 39023610
Nineteen structures averaged at least 3.5 on a four-point scale and the remainder at least 3.0; review author affiliations and exact software version before procurement use.
Costs and setup
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.
No separate named-product payment identified in reviewed CMS material
Centers for Medicare & Medicaid Services · United StatesBuild a local total-cost and value model; do not infer reimbursement from FDA clearance.
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.
Buyer worksheet
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.
