20080202200 | Calibrating tracking systems to remove position-dependent bias - A method for removing position-dependent bias from tracking systems computes invertible transformations between a tracking system and a reference system, and applies an inverse of the transformation to measurements in the tracking system to estimate the locations of reference points in the reference system and to determine relative bias at the measured points. | 08-28-2008 |
20080279438 | Inverse planning using optimization constraints derived from image intensity - A method of automatically identifying a region of differing intensity in a functional image is described. | 11-13-2008 |
20090005668 | Non-invasive method for using 2D angiographic images for radiosurgical target definition - A non-invasive method and system for using 2D angiographic images for radiosurgical target definition uses non-invasive calibration devices and methods to calibrate an angiographic imaging system and a six-parameter registration algorithm to register angiographic images with 3D scan data for radiation treatment planning. | 01-01-2009 |
20100104068 | SEQUENTIAL OPTIMIZATIONS FOR TREATMENT PLANNING - A method and apparatus for radiation treatment planning are described. The method includes receiving a plurality of radiation treatment-planning parameters, and sequentially optimizing the plurality of radiation treatment-planning parameters. | 04-29-2010 |
20120106704 | METHOD AND APPARATUS FOR TREATING A TARGET'S PARTIAL MOTION RANGE - 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. | 05-03-2012 |
20120109608 | METHOD AND APPARATUS FOR SELECTING A TRACKING METHOD TO USE IN IMAGE GUIDED TREATMENT - A treatment delivery system or a simulation system simulates treatment of a patient, including testing the ability of one or more tracking methods to track a target position during the simulation. The system then presents simulation results to a user, the simulation results indicating whether any of the one or more tracking methods will successfully track the target position during treatment delivery. | 05-03-2012 |
20120203053 | SEQUENTIAL OPTIMIZATIONS FOR TREATMENT PLANNING - A method and apparatus for radiation treatment planning are described. The method includes receiving a plurality of radiation treatment-planning parameters, and sequentially optimizing the plurality of radiation treatment-planning parameters. | 08-09-2012 |
20130101082 | APPARATUS FOR GENERATING MULTI-ENERGY X-RAY IMAGES AND METHODS OF USING THE SAME - Apparatus for generating multi-energy x-ray images and systems and methods for processing and using multi-energy x-ray images are provided for treating a target, e.g., a tumor, for image-guided radiation therapy. An image-guided radiation therapy system is provided including a treatment delivery system, a multi-energy imaging system, and a system processor. The treatment delivery system includes a radiation source configured to generate treatment radiation beams. The multi-energy imaging system is configured to generate a first set of image data of the patient using imaging radiation at a first energy level and a second set of image data of the patient using imaging radiation at a second energy level. The system processor is configured to process the first and second sets of image data to generate an enhanced image of the patient and to direct the treatment delivery system based on information obtained from the enhanced image. | 04-25-2013 |
