3D Dosimetry based on a new optical approach for dosimetry gels: Use of the polarisation ratio of the scattering light
Original language description
Several investigations have been carried out by researchers over past two decades to evaluate and perform the reading of gel dosimeters for the three-dimensional measurement of radiation fields. Imaging of the gels has been successfully accomplished with clinical MRI and via laser-based optical scanning using transmission of the light. We report here the methodology and results of a preliminary study carried out to evaluate the utility of a new and simplified approach to make 3D imaging of gel radiation dosimeters based on the scattering light analysis. For the purpose of this initial investigation, nMAG gel has been studied by our method. All pictures were evaluated through a region-of-interest (ROI) analysis to obtain the average change in image density in each sample as a function of the radiation dose. These measured ROI values were subjected to any fit and given a calibration dose and a spatial resolution. This way, we performed a 3D reconstruction of a dosimeter gel.
