1. A radiation treatment system, comprising:
- a rotatable gantry;
a treatment source;
a cone-beam radiation source coupled to the rotatable gantry;
a flat-panel imager coupled to the rotatable gantry, wherein the flat-panel imager is operable to capture image projection data of a patient;
a first logic that reconstructs a cone-beam computer tomography (CT) volumetric image data based on the image projection data;
a patient support to support the patient; and
a second logic configured to control the patient support and place the patient in an operative position to begin a treatment based on the cone-beam CT volumetric image data or the image projection data.

Abstract
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.

10. A method to prepare for a clinical treatment, comprising:
-
obtaining image projection data from transmitting at least a portion of a cone-beam from a radiation source through a target volume onto a flat panel imager; generating cone-beam computer tomography (CT) volumetric image data based on the obtained image projection data; and placing a patient in an operative position to begin the clinical treatment based on the cone-beam CT volumetric image data or the image projection data. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
