  • Patent number: 10413754
    Abstract: Radiotherapy is one of the most effective treatments for cancer and its success depends critically on accurate targeting and delivery of the correct radiation dose. Accurate dosimetry is therefore essential to maintain and improve patient survival rates. However, size and long wait times currently limit water and graphite based calorimeters to standards laboratories leaving field-based dosimetry to ionization chamber measurements which depend upon a reference field-specified calibration factor. It would therefore be beneficial to provide radiotherapy equipment operators a direct approach of clinical reference dosimetry wherein the dosimeter provides increased independence on dose, dose rate, radiation energy, and energy type, etc. It would be further beneficial for such novel clinical dosimeters to be compact, function as secondary standards used routinely for measurements and allow radiotherapy doses to be measured directly and in an absolute manner.
    Type: Grant

    Date of Patent: September 17, 2019
