Elekta Versa HD User Manual — Technical Paper

2. System Components and Controls

• Gantry and treatment head: Beam generation, collimation, MLC (high-definition Agility MLC with 160 leaves), imaging panel/EPID.
• Patient support: Couch with 6 degrees of freedom, indexing, load limits.
• Control console: Treatment console software, user roles (therapist, physicist, dosimetrist), emergency stop.
• Imaging systems: kV CBCT, onboard imaging, image registration tools.

Monthly (Medical Physicist)

• MLC Leaf Position Accuracy: Winston-Lutz test using the IsoCheck phantom. Tolerance: <0.35mm.
• Output Constancy: Check flattening filter free (FFF) beam profiles.
• Couch Walkout: Extend couch to max overhang; measure sag. Manual limit: 2mm over 120cm.

2. Fragmented advanced technique coverage

• SRS cone collimator setup is split across Chapter 8 (hardware) and Chapter 14 (treatment planning interface), with no single end‑to‑end reference.
• VMAT gantry speed modulation is explained in theory but lacks practical troubleshooting (e.g., “why did the beam hold?”).
