  • Calibration of hypoxic region focused radiotherapy treatment plans
    Patent number: 10960230
    Abstract: The present invention features calibration methods for radiotherapy treatment plans. An image-guided radiotherapy system for tumor treatment featuring a hypoxic-region-focused (HRF) radiation dose is calibrated using a phantom. The treatment plans may also feature a boosted dose to the resistance region of the tumor. The HRF radiation dose may be greater than 120% of a predetermined prescribed radiation dose for the tumor.
    Type: Grant

  • Calibration of radiation therapy treatment plans for a system
    Patent number: 10668301
    Abstract: A simple metric, the mean absolute dose deviation (“MADD”), for characterizing dose-volume histograms (“DVH”) is disclosed. The MADD facilitates the use and the comparison of DVHs. The MADD is defined as the average of absolute differences between all points of a DVH and a dose point of a specified reference dose range. The MADD is a generalized metric free from distribution assumptions, and it is directly applicable to all types of structures.
