A MULTI-MODE CONE BEAM CT RADIOTHERAPY SIMULATOR AND TREATMENT MACHINE WITH A FLAT PANEL IMAGER

摘要

A multi-mode cone beam computed tomography radiotherapy simulator and treatment machine is disclosed. The radiotherapy simulator and treatment machine both include a rotatable gantry on which is positioned a cone-beam radiation source and a flat panel imager. The flat panel imager captures x-ray image data to generate cone-beam CT volumetric images used to generate a therapy patient position setup and a treatment plan.
