High-precision, reproducible immobilization with MRI fusion for target definition.
From scan to setup
Simulation
Site-specific simulation and treatment set-up parameters, the treatment reactions that influence setup, and the procedure-specific aids used to reproduce the plan. Tap a card to expand the detail.

Mask immobilization with shoulder control to spare organs at risk and reproduce the neck position.
Reproducible arm position on an inclined breast board; breath-hold for left-sided cardiac sparing.
Motion management is central — 4D-CT and respiratory control define the moving target.
Breath-hold or compression controls respiratory motion of upper-abdominal targets.
Bladder and rectal filling protocols and fiducials give day-to-day reproducibility.
Acute and late skin effects depend on dose, fractionation, and the volume of skin in the field.
Reactions follow the irradiated mucosa — head & neck, esophagus, bowel, or bladder.
Fatigue, marrow suppression, and late fibrosis shape both care and setup reproducibility.
Devices that fix external position so the simulation scan and every fraction match.
Devices that manage internal motion and enhance target visualization at simulation.
Aids that modify the dose distribution or provide an internal reference for setup.
