  • Interactive computer-aided editor for compensators used in radiotherapy treatment planning
    Patent number: 10850119
    Abstract: When constructing compensators for radiation therapy using ion or proton radiation beams, a computer-aided compensator editing method includes overlaying an initial 3D compensator model on an anatomical image of a target mass (e.g., a tumor) in a patient, along with radiation dose distribution information. A user manipulates pixels or voxels in the compensator model on a display, and a processor automatically adjusts the dose distribution according to the user edits. The user iteratively adjusts the compensator model until the dose distribution is optimized, at which time the optimized compensator model is stored to memory and/or output to a machining device that constructs a compensator from the optimized model.

  • Simultaneous multi-modality inverse optimization for radiotherapy treatment planning
    Patent number: 9155908
    Abstract: When performing multimodal radiotherapy planning, an optimizer (36) concurrently optimizes a combined treatment plan that employs an intensity modulated radiotherapy (IMRT) device (30) and an intensity modulated proton therapy (IMPT) that respectively generate a photon beam and an ion beam for treating a volume of interest (18) in a patient (34). A simulator (40) iteratively generates multiple variations of a simulation model (44) according to optimization parameters that are varied by the optimizer (36) until the simulation model (44) satisfies user-entered treatment objective criteria (48) (e.g., maximum dose, does placement, etc.
