  • Quality assurance for MR-Linac
    Patent number: 12343566
    Abstract: The present disclosure includes procedures to automate quality assurance testing for radiotherapy equipment that includes MR-Linac devices that are agnostic as to the manufacturer and vendor of the equipment. The present disclosure includes a process for performing a validation procedure for the linear accelerator of the MR-Linac device. The present disclosure includes a process for analyzing quality of the images produced by the MR imaging device of the MR-Linac device. The present disclosure includes a process for combining performance of a validation procedure for the linear accelerator of the MR-Linac device and the analysis of the quality of the images produced by the MR imaging device of the MR-Linac device.
    Type: Grant

  • System and method for commissioning of a beam model for a three dimensional radiation therapy treatment planning system
    Patent number: 9087224
    Abstract: A system and method for commissioning of a beam model for a three dimensional radiation therapy treatment planning system is described. The system includes an intensity modulated radiotherapy (IMRT) unit for generating a two dimensional intensity modulated beam pattern, a two dimensional diode array for detecting a two dimensional dose map for the beam pattern, and a processor configured to execute instructions for iteratively adjusting one or more parameters for the beam model, in order to increase agreement between the detected dose map and a calculated dose map calculated using the beam model.
