1. An apparatus, comprising:

  • a radiation treatment system capable of implementing a treatment plan, the system comprising;

    a frame;

    a rotatable gantry coupled to the frame;

    a high-energy radiation source coupled to the rotatable gantry to radiate a patient with therapeutic radiation;

    a cone-beam radiation source coupled to the rotatable gantry to radiate the patient;

    a flat-panel imager coupled to the rotatable gantry, wherein the flat-panel imager is operable to capture image projection data of the patient from the cone-beam radiation source to generate cone-beam computed tomography (CT) volumetric image data of the patient; and

    a computing unit, coupled to the rotatable gantry via a communications network, to store the image projection data captured by the flat-panel imager.
