Patent number: 10987523Abstract: In certain embodiments novel sparse orthogonal collimators (SOCs) for use in radiotherapy are provided. In certain embodiments the SOCs comprise 2 layer 4 bank orthogonal collimators with 2-8 leaves in each of the 4 banks. Instead of using the limited heuristic approach to create jaw-only IMRT, a novel fluence map optimization method is provided based on wavelet decomposition and this method is used for IMRT. An algorithm to simplify the fluence maps with minimal and predictable dose quality compromise is also provided.Type: GrantFiled: October 21, 2016Date of Patent: April 27, 2021Assignee: The Regents of the University of CaliforniaInventors: Ke Sheng, Dan Nguyen, Dan Ruan

Publication number: 20200075148Abstract: A method and system for generating a treatment plan are disclosed herein. A computing system receives a plurality of dose volume histograms for a plurality of patients and a plurality of volumetric dose distributions corresponding to the plurality of dose volume histograms. The computing system generates a volumetric dose prediction model using a neural network by learning, by the neural network, a relationship between a plurality of dose volume histograms for the plurality of patients and the corresponding plurality of volumetric dose distributions. The computing system receives a candidate dose volume histogram for a target patient. The computing system infers, via the volumetric dose prediction module, a volumetric dose prediction distribution matching the candidate dose volume histogram. The computing system generates a recommendation based on the inferred volumetric dose prediction distribution.Type: ApplicationFiled: September 3, 2019Publication date: March 5, 2020Applicant: The Board of Regents of the University of Texas SystemInventors: Dan Nguyen, Steve Jiang
