More Information
Summary:Systems and methods are disclosed for optimization of radiotherapy treatments. Example operations for treatment planning include: obtaining first optimization problems for providing radiotherapy treatment to a human subject; performing dose optimization for delivery of the radiotherapy treatment to a treatment (target, low dose) area of the human subject, by performing at least a first pass and a second pass; and generating treatment plan data based on at least one of the multiple solutions provided by the second pass. In an example, the dose optimization includes: converting the first optimization problems into a first problem matrix; performing the first pass by solving the first optimization problems on parallel processing hardware; combining multiple solutions to the first optimization problems to produce second optimization problems; converting the second optimization problems into a second problem matrix; and performing the second pass by solving the second optimization problems on the parallel processing hardware.
