Gel dosimetry involves three major steps in order to obtain a dose distribution: (a) after fabrication the gel is poured into an (antropomorphically shaped) cast and into calibration vials; (b) the phantom is irradiated with a specific dose distribution and calibration samples are irradiated to known doses; (c) the irradiated gel dosimeter phantoms are scanned with an appropriate and optimized scanning technique (magnetic resonance imaging (MRI), optical computerized tomography (optical-CT), x-ray computerized tomography (x-ray CT) or ultrasound; (d) finally the data are used to produce an image of the irradiated dose distribution.
