INTENSITY MODULATED ARC THERAPY WITH CONTINUOUS COUCH ROTATION/SHIFT AND SIMULTANEOUS CONE BEAM IMAGING

摘要

A radiation therapy system that includes a radiation source that moves about an object and directs a beam of therapeutic radiation towards the object and an imaging source that moves about the object and directs a beam of imaging radiation towards the object. The system further includes a table upon which the object is positioned, the table being translationally and rotationally movable. The system also includes 1) a first imager for receiving radiation passing through the object that was generated by the therapeutic radiation source and for forming a first image information therefrom and 2) a second imager for receiving radiation passing through the object that was generated by the imaging source and for forming a second image information therefrom, wherein the first image information and the second image information are formed simultaneously.
