Abstract:
1. A combined system for planning and delivering X-ray therapy to a patient, the system including: a CT imaging subsystem defining at least one slice plane so that data generated by the CT imaging subsystem can be used to create images relative to the slice plane so that a target region of the patient can be (a) determined for treatment during a planning phase and (b) imaged during treatment during a treatment phase, wherein the CT imaging subsystem includes at least two sources of X-rays; and a radiation therapy subsystem including a source for delivering a beam of therapeutic X-rays to the target region of the patient during treatment; wherein the radiation therapy subsystem provides the beam of the therapeutic X-rays in a direction which is in a plane that is substantially fixed relative to the slice plane of the CT imaging subsystem and substantially coplanar with the slice plane of the CT imaging subsystem so that the targeted region can be imaged, and exposed to the beam of therapeutic X-rays without the necessity of moving the patient.
