FDA-cleared profile
Siemens Medical Solutions USA, Inc.
NAEOTOM Alpha is a photon-counting CT system for diagnostic cross-sectional imaging, treatment and interventional support, and low-dose lung-cancer screening under approved protocols.
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 K233657 before acceptance.
exact submission · checked 2026-09-03Later product-family features are not evidence that this cleared release includes them.
DICOM CT workflow with advanced image objects; validate PACS, RIS, worklist, quantitative consistency, reconstruction, and downstream software support.
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. K233657 explicitly does not support radiation-therapy planning, unlike K243523. The scanner is not the principal guidance method for invasive procedures, and product-family literature does not establish every exact-version outcome.

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.

Monitor by exact hardware, software and model version, patient population, anatomy, protocol, operator, input quality, output edits or overrides, failed studies, repeat acquisition or rework, downstream impact, downtime, incidents, recalls, and updates. Track the limits that matter for this product: K233657 explicitly does not support radiation-therapy planning, unlike K243523. The scanner is not the principal guidance method for invasive procedures, and product-family literature does not establish every exact-version outcome.

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 dose-delivery 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 dose-delivery function. Use the task-specific endpoints and tested population reported below.
No contextualized exact-version metric has completed evidence review. Regulatory-document values, when available, are shown above with their limitations.

Technology-level evidence; K233657 explicitly excludes radiation-therapy planning.
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 8 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.
