GE Revolution CT Family
Successor platform to the LightSpeed family. Revolution generations introduced wider-coverage detectors (up to 160 mm Z-axis on Revolution HD and CT), faster rotation, and generation-advanced iterative reconstruction (ASiR-V, DLIR). GE's current CT platform across entry-to-flagship tiers.
Variants (each a separate System Card)
- Revolution HD — 64-slice, Revolution-generation detector + tube
- Revolution Apex — 256-slice, single-heartbeat cardiac, 160 mm Z-axis coverage
- Revolution CT (standard) — 256-slice, pre-Apex generation
- Revolution Frontier — entry-tier Revolution
- Revolution Ascend — compact, cardiac-capable
What makes Revolution different from LightSpeed
- Detector architecture — Gemstone detector generation, higher z-axis coverage
- Tube — upgraded from Performix Pro to Gemstone Performix (higher heat capacity)
- Reconstruction — ASiR-V (Revolution era) and DLIR (deep-learning reconstruction, late Revolution / Apex)
- Cardiac — SnapShot Freeze motion correction + SnapShot Pulse gating improvements
- Dose — multiple tiers of dose reduction software
Clinical positioning
Revolution HD addresses the same market as the VCT XT refurb — 64-slice CT with cardiac + ASiR. Revolution Apex competes with Siemens Force and Canon Aquilion ONE in the ultra-high-end segment where single-heartbeat cardiac and whole-organ dynamic perfusion matter.
Service reality
Newer tube + detector generations vs VCT, so parts ecosystem is less deep on the refurb side. Service-contract economics still favor newer Revolutions since they're still in OEM manufacture.
