Patent number: 10603511Abstract: A system and method for automatically generating radiation therapy treatment plans including one or more processors configured to capture geometries of organs at risk and a target volume specific to a subject, and use a shape-based algorithm to mine (152) a knowledgebase (38) of previously constructed treatment plans for similar geometries to the subject. The system and method interfaces (154) dosimetric information from a plan with a similar geometry as a patient specific starting point for a progressive tuning optimization algorithm resulting in fewer iterations. The progressive tuning algorithm (156, 158, 162) generates an optimized treatment plan. The optimized plan is evaluated against treatment goals. Trade-off plans are generated (164) create alternative plans according to unmet treatment goals.Type: GrantFiled: December 3, 2015Date of Patent: March 31, 2020Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Karl Antonin Bzdusek, Prashant Kumar, Todd McNutt

Patent number: 8094895Abstract: A method for selecting vertices for performing deformable registration of imaged objects is provided. The selected vertices form corresponding pairs, each pair including a vertex from a first imaged object and a vertex from a second imaged object. The corresponding vertex pairs are sorted in order of distance between the vertices making up the corresponding vertex pair. The corresponding vertex pair with the greatest distance is given top priority. Corresponding vertex pairs that lie within a selected distance from the selected corresponding vertex pair are discarded. In this manner, the number of vertex pairs used for deformable registration of the imaged objects is reduced and therefore allows for processing times that are clinically acceptable.Type: GrantFiled: May 31, 2006Date of Patent: January 10, 2012Assignee: Koninklijke Philips Electronics N.V.Inventors: Michael Kaus, Todd McNutt, Vladimir Pekar

Patent number: 7536041Abstract: A delineation of a structure of interest can be performed by fitting 3D deformable models, for example, represented by polygonal measures, to the boundaries of the structure of interest. The deformable model fitting process is guided by minimization of the sum of an external energy, based on image feature information, which attracts the mesh to the organ boundaries and an internal energy, which preserves the consistent shape of the mesh. A frequent problem is that the images do not contain sufficient reliable image feature information, such as image gradients, to attract the mesh. According to the present invention, manually drawn attractors in the form of complete or partial contours corresponding to boundaries of the structure of interest are placed into the images which do not contain sufficient feature information. These attractors may easily be discriminated by a subsequent segmentation process.Type: GrantFiled: June 9, 2004Date of Patent: May 19, 2009Assignee: Koninklijke Philips Electronics N.V.Inventors: Vladimir Pekar, Michael Reinhold Kaus, Todd McNutt

Publication number: 20090046831Abstract: An image-guided irradiation system has a support stage, a stage-positioning assembly connected to the support stage, an x-ray source attached to a support arm in which the support arm is movable relative to the support stage, a flat-panel x-ray detector disposed proximate the support stage, and at least one of a collimator or an x-ray lens selectively disposable between the x-ray source and the support stage. The x-ray source is suitable to provide an imaging beam of X-rays at a first photon energy and is suitable to provide an irradiation beam of X-rays at a second photon energy. The collimator or x-ray lens is structured and arranged to define at least a width of the irradiation beam when it is disposed between the x-ray source and the support stage while the x-ray source is in operation.Type: ApplicationFiled: March 12, 2007Publication date: February 19, 2009Applicant: The John Hopkins UniversityInventors: John Wai-chiu Wong, Todd McNutt, Elwood P.
