摘要： A method and apparatus for targeting a cancerous lesion or tumor during radiotherapy or radiosurgery compπsing the steps of pre-operatively scanning the surgery site using one of magnetic resonance imaging, positron emission tomography or computed tomography to identify the tumor and plan the surgery Intra-operatively scanning the site with ultrasound and overlaying the live ultrasound scan on top of the pre-operative scan Registration of the two images is achieved using image deformations and an average arbitrary normal patient image atlas The method allows registration of the multimodal images for the tracking of the target duπng surgery.

摘要： A computing system determines a full motion range of a target, wherein the full motion range of the target defines an internal target volume (ITV). The computing system identifies a partial motion range of the target, wherein the partial motion range is a subset of the full motion range of the target. The computing system generates a partial-ITV based on the identified partial motion range, wherein the partial-ITV is a volume swept by the target as the target moves through the partial motion range, the partial-ITV being smaller than the ITV. The computing system generates a treatment plan to deliver treatment to the partial-ITV.

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.
