The gantry rotates 360 degrees around the patient. The treatment head contains the dual-filter system, ionization chambers for dose monitoring, and the Agility MLC system. The Agility collimator provides 5 mm leaf widths across the full field, offering low leaf leakage to enhance patient safety. Patient Positioning and Table Systems

This drastically shortens treatment times for stereotactic body radiotherapy (SBRT) and stereotactic radiosurgery (SRS), minimizing the impact of intra-fraction patient motion. XVI (X-ray Volume Imaging)

Clean the patient couch top, check couch rails for debris, and verify optical tracking targets.

Position the patient using the specific immobilization devices noted in the plan.

The operator must visually inspect the registration windows (Axial, Sagittal, Coronal) and manually adjust the matching box over the Target Volume (PTV).

Functional descriptions of the MV imager and the XVI (X-ray Volume Imaging) system for 3D/4D kV CBCT. Treatment Couch:

The user manual is also the foundation for competency checklists. Most clinics derive their annual therapist competency exam directly from the manual.
