Radiotherapy system with integrated static computed tomography imaging

Abstract

A radiation treatment system includes a radiation delivery system including a rotatable gantry that is coupled to a static portion of the radiation treatment system and a radiation source that directs treatment radiation to a target volume and is mounted on the rotatable gantry for rotation about the target volume. The radiation treatment system further includes a computed tomography (CT) imaging system that generates portions of a CT scan of a region of patient anatomy that includes the target volume, wherein the CT imaging system includes an arcuate array of x-ray detectors, and an array of x-ray sources positioned around the target volume, wherein each x-ray source in the array of x-ray sources is oriented to direct imaging x-rays towards a different portion of the arcuate array of x-ray detectors.
