FDA-cleared profile
Varian Medical Systems, Inc.
AI Segmentation version 2.0 generates initial CT organ-at-risk contours for head and neck, thorax, abdomen, and pelvis for review, editing, and approval in Eclipse.
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 data-flow, identity, audit, encryption, retention, support-access, vulnerability-management, backup, and incident-response evidence.
Map the installed model, build, options, population, anatomy, inputs, and outputs to K211881 before acceptance.
exact submission · checked 2026-09-03Later product-family features are not evidence that this cleared release includes them.
Cloud web application integrated with Eclipse for contour export; validate DICOM routing, structure naming, image association, browser and identity controls, editing, approval, and downtime procedures.
exact submission · checked 2026-09-03Test 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 application does not provide clinical decisions, medical advice, or treatment-plan evaluation. All contours require expert review, editing as needed, and physician approval; no animal or clinical study was performed.

Evidence
Metrics are shown only when they are tied to a source, endpoint, population, and tested product version.
Sensitivity is not the primary applicable endpoint for this acquisition, reconstruction, segmentation, planning, guidance, or quantitative-biomarker function. Use the task-specific endpoints and tested population reported below.
Specificity is not the primary applicable endpoint for this acquisition, reconstruction, segmentation, planning, guidance, or quantitative-biomarker function. Use the task-specific endpoints and tested population reported below.

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 configuration was found. Obtain a written quote separating hardware or license basis, enabled features, implementation, interfaces, infrastructure, training, service, upgrades, renewal, consumables, and exit costs.
No separate named-product payment identified in reviewed public material

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.

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 materials, current product-family sources, selected clinical literature, reimbursement context, and exact-identifier recall candidates were reviewed. Pricing, contracted services, enabled options, final security architecture, and local interoperability remain organization-specific evidence. Automated exact-name discovery found 20 PubMed and 5 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.
