摘要： PROBLEM TO BE SOLVED: To provide a method to direct a surgical means, for which an X-ray linear accelerator is used, to the target region of a patient. SOLUTION: A stated device selectively irradiates the target (18) in the patient (14). The three-dimensional image of an imaging region (16) around the target is provided. A beam device (20) emits a collimating beam. Beams (26 and 28) for the diagnosis pass the imaging region at angles which are already known to each other and not zero. Thus, the image of a projected shadow in the imaging region is obtained. The electronic display of the image is compared to reference data in which the target (18) is arranged. The focal point of the collimating beam is adjusted onto the target region, and relative locations of the beam device and the physiological body are regulated. The comparison is repeated with a short period of time interval, and the regulation is repeated with the focal point of the collimating beam adjusted to the target region (16) when required.

摘要： A method and apparatus for locating an internal target region during treatment without implanted fiducials is presented. The method comprises producing a plurality of first images that show an internal volume including the internal target region, then producing a live image of the internal volume during treatment and matching this live image to one of the plurality of first images. Since the first images show the internal target region, matching the live image to one of the first images identifies the position of the target region regardless of whether the second image itself shows the position of the target region. The first images may be any three-dimensional images such as CT scans, magnetic resonance imaging, and ultrasound. The live image may be, for example, an x-ray image. The invention may be used in conjunction with a real-time sensor to track the position of the target region on a real-time basis.

摘要： There is disclosed herein a technique for carrying out stereotaxic radiosurgery or radiotherapy on a particular target region within a patient by a radiosurgical/radiotherapeutic beam of radiation which is at least intermittently directed along a beam path through the target region. One particular beam generating arrangement illustrated is carried by a robotic arm which is movable in at least three dimensions. In accordance with one embodiment disclosed herein, a method and apparatus are provided for moving the robotic arm and beam generating arrangement along a predetermined, non-circular and non-linear path transverse to the beam path while, at the same time, the beam path is directed into the target region. In this way, the radiosurgical/radiotherapeutic beam can be directed through the target region from particular treatment points along the transverse path so as to define a non-spherical target region. In accordance with a second embodiment, the apparatus disclosed herein includes an emergency stop arrangement separate from and independent of the controlling the robotic arm controller for automatically stopping all movement of the robotic arm and turning off the beam if the robotic arm deviates from its intended transverse path. In a third embodiment, the apparatus utilizes a plurality of target locating beams of radiation apart from but cooperating with the radiosurgical/radiotherapeutic beam to accurately and continuously locate the target region in substantially real time.
