Abstract
A method of and system for locating a targeted region in a patient uses a CT imaging subsystem and a radiotherapy subsystem arranged so the targeted region can be imaged with the imaging system and treated with a beam of therapeutic X-ray radiation using a radiotherapy subsystem. The beam of therapeutic X-rays is in a plane that is substantially fixed relative to, and preferably coplanar with, a slice plane of the CT imaging subsystem so that the targeted region can be imaged during a planning phase, and imaged and exposed to the therapeutic X-rays during the treatment phase without the necessity of moving the patient.
Claims23
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.
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 two sources of X-rays and is programmed and adapted to use the two sources to create a stereoscopic image of the target region;
- 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 so that the targeted region can be imaged, and exposed to the beam of therapeutic X-rays without the necessity of moving the patient, wherein the radiation therapy subsystem includes a support for pivoting a source of the beam of therapeutic X-rays so that the beam can be directed from a predetermined angle and the CT imaging subsystem includes at least two sources of X-rays or a moving electron beam source.
A method of locating a targeted region in a patient using a CT imaging subsystem, and treating the targeted region with therapeutic X-ray radiation using a radiotherapy subsystem, comprising:
- providing the therapeutic X-rays in a direction within a plane which is substantially fixed relative to a 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 during a planning phase, and imaged and exposed to the therapeutic X-rays during a treatment phase without the necessity of moving the patient, wherein the CT imaging subsystem includes at least two sources of X-rays.
A method of planning and delivering X-ray therapy to a patient, comprising:
- defining at least one slice plane of a CT imaging subsystem so as 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, using at least two sources of X-rays;
- delivering a beam of therapeutic X-rays to the target region of the patient during the treatment phase;
- wherein the beam of the therapeutic X-rays is delivered in a direction which is in a plane that is substantially fixed relative to the slice plane so that the targeted region can be imaged, and exposed to the beam of therapeutic X-rays without the necessity of moving the patient;
- pivoting a source of the beam of therapeutic X-rays so that the beam can be directed from a predetermined angle;
- and
- further including using the two sources to create stationary views of the target region and create a stereoscopic image of the target region.
