Abstract
With the recent advances of radiotherapy treatment techniques at center, a 3D dosimeter technique was analyzed for its feasibility, precision and accuracy. The dosimeter system was based on the NIPAM polymer gel. This gel was analyzed for its effectiveness in quantifying the 3D dose distribution produced by an IMRT treatment. The plan for this treatment was produced by a treatment planning computer, where by measured dose distributions determined from the polymer gel were compared to the calculated planned data. The PTV within the treatment was the prostate and the OAR was the femoral heads, rectum and bladder; a 7 field treatment technique was applied.
A calibration curve was generated and used to determine the dose within the polymer gel. Cuvita were calibrated to different energies and different dose rates to test for an energy and dose rate dependence of the gel. The gel was found to be independent of both energy and dose rate.
