    摘要： An apparatus and method for optimizing a workspace of a radiation treatment delivery system. An optimized treatment plan is generated for delivering a dose of radiation to a volume of interest (“VOI”) in a patient using fewer changes to a treatment plan parameter during delivery of the dose of radiation then available to a radiation treatment delivery system. The optimized treatment plan limits a number of adjustments to the treatment plan parameter during delivery of the dose of radiation. Prior to delivery, the optimized treatment plan is analyzed to determine whether a quality of the optimized treatment plan is acceptable.

    摘要： A method for precision registration of X-ray images to cone-beam CT scan for image-guided radiosurgery includes acquiring 2-D pre-treatment X-ray images of a region of interest, acquiring a 2-D X-ray image of the region of interest at approximately a time of treatment, registering the 2-D X-ray image with a corresponding 2-D pre-treatment X-ray image to obtain a 2-D registration result at approximately the time of treatment, and converting the 2-D registration result into a 3-D tracking result to track the region of interest.

    摘要： A wireless treatment target positioning system for therapeutic radiation treatment includes a patient positioning system and a treatment target locating system. The treatment target locating system includes a room beam coordinate system and a localizing system. The room beam coordinate system includes devices for generating laser beams intersecting at a single point that is spatially coincident with an iso-center of the treatment system. The localizing system includes a movable reference object and a localizer for detecting and determining the position of the movable reference object. A method of positioning a treatment target to the iso-center of the treatment system includes a simulation process and real treatment positioning process. The simulation process includes positioning the treatment target to an iso-center of a simulation system and marking intersection points where laser beams intersect with an exterior of the patient's body. The real treatment positioning process includes determining the position of the intersection points marked on the exterior of the patient body, determining a treatment position for positioning the patient such that the treatment target is aligned with the iso-center of the real treatment system, and positioning the patient to the treatment position.
