  • Method and system for optimized reconstruction of treatment dose based on integrated exit-transit images of radiation fields taken during treatment
    Patent number: 10994155
    Abstract: An optimized method and system to compute the dose to a patient (2) given a captured integrated exit-transit image (5) of the radiation rays (4) traveling from the source of x-rays (1) through the patient (2) to the imaging device (3) to product the exit-transit image (5). Each radiation field image (5) is transformed (6,8,10,12) to multiple images (7,9,11,13) for each phantom thickness (26) that was measured with the imaging device (3) for a range of field sizes (21). Given the water equivalent path (22) through the patient for a ray (4) reaching a pixel (15, 16), the final pixel value (19) is interpolated from the images (9, 11) that bracket the water equivalent path through the patient (22). Adaptive feedback calibration measures are carried out effectively ameliorate the detrimental effects of off axis attenuation of pixel values.

  • Radiation therapy dosimetry quality control process
    Patent number: 6853702
    Abstract: A treatment verification process for radiation therapy consisting of measuring each of the radiation beams that are to be applied to the patient by making a calibrated image of the field for each beam. The measured beams are then processed and converted to relative monitor units. Software like a treatment planning system is then used to compute the dose to the patient for comparison with the intended treatment prescription.
