Varian Trilogy
Family: Varian Trilogy · Modality: Linear Accelerator (Rad Onc)
Mid-2000s Varian premium linac — Clinac chassis with high-dose-rate (HDR) mode (1000 MU/min) and early SRS capabilities. Bridges the Clinac iX and TrueBeam generations. Common "iX Trilogy" branding indicates an iX platform with Trilogy's HDR/SRS package. Displaced by TrueBeam STx.
Variant-specific considerations
- HDR mode 1000 MU/min (vs 600 standard)
- SRS cone and MLC support
- OBI on-board imaging standard
- Substantial SRS-capable installed base; many displaced by TrueBeam STx
Parts
