摘要：
A radiation therapy system that includes a radiation source (409) that movesabout a path and directs a beam of radiation towards an object and a cone-beamcomputer tomography system (400). The cone-beam computer tomography systemincludes an x-ray source (402) that emits an x-ray beam in a cone-beam formtowards an object to be imaged and an amorphous silicon flat-panel imager(404) receiving x-rays after they pass through the object, the imagerproviding an image of the object. A computer is connected to the radiationsource and the cone beam computerized tomography system, wherein the computerreceives the image of the object and based on the image sends a signal to theradiation source that controls the path of the radiation source.
