Siemens SOMATOM go.Top
Family: Siemens SOMATOM go · Modality: CT
128-slice mid-premium CT built on the go. platform architecture. Tablet-based operator workflow (mobile console on the gantry and the control room), ADMIRE iterative reconstruction, and whole-chest / whole-abdomen coverage for routine and cardiac-capable clinical work. Positioned above Definition AS as the current mid-tier replacement.
Platform highlights
- Tablet-controlled workflow — mobile tablets at the gantry and console drive the exam; the host workstation is still present for advanced reconstruction but most of the day-to-day scan control happens on the tablet.
- 128-slice detector — 57.6 mm Z-axis coverage per rotation (acquired slices), reconstructed as 128 × 0.6 mm.
- Vectron tube (shared generation with Definition Edge / Drive) — rotating-anode, liquid-bearing design.
- ADMIRE — Siemens' second-generation model-based iterative reconstruction for dose reduction.
- Cardiac capable — retrospective and prospective gating; 66 ms effective temporal resolution with adaptive cardio.

Parts
Clinical positioning
Community and mid-size hospital CT where 128-slice coverage is sufficient — routine body, neuro, oncology staging, cardiac screening, vascular runoff. Not a Flash/Force-class cardiac platform: Force remains the top-tier choice for beta-blocker-free coronary CTA.
Relationship to siblings
- SOMATOM Definition AS — predecessor-class. Similar clinical scope, older host architecture.
- SOMATOM Definition Flash — dual-source sibling, different tier.
- go.Now / go.Up / go.All — lower-slice members of the go. family.
