Target-tracking deliveries on an Elekta linac: a feasibility study.

Journal article

A target-tracking, intensity-modulated delivery on an Elekta MLCi system was assessed by film measurement with a simulated target-motion trajectory. A toroidally shaped idealized target surrounding an organ at risk necessitating multiple field segments to irradiate the target and spare the organ at risk was defined in a solid-water phantom. The phantom was programmed to move following a reproducible 2D elliptical trajectory in the beam's-eye view with a period of 10 s. Static and target-track...
