Siemens SOMATOM Definition AS
Family: Siemens SOMATOM Definition · Modality: CT
Single-source CT scanner in the SOMATOM Definition family — 40, 64, and 128 slice configurations depending on year/tier. Contrast with the dual-source SOMATOM Definition Flash / Force line: the AS was the mainstream workhorse, the Flash/Force family was the dual-source cardiac / high-pitch premium. Large global install base; refurb favorite.
Variant-specific considerations
- Typically 64- or 128-slice depending on configuration
- CARE dose-reduction suite standard
- IRIS / SAFIRE iterative reconstruction as software licensing tiers
- Successor-class is SOMATOM go.Top / go.All and the Definition AS+ upgrade path; SOMATOM X.cite is the current single-source premium successor for wide-bore / workflow-automation use cases
