The major challenge in radiotherapy is to deliver and quantify an accurate dose of radiation to the tumour. Dosimetry is the practice of quantitatively determining the energy deposited in a medium by an ionising radiation. Several dosimetric techniques are available to measure the radiation dose, but they have limitations. In particular, the non-tissue equivalence of the detector housing/material and the sensitive volume leads to perturbations of the radiation fluence and necessitates correction factors. Another constraint placed on conventional dosimetric techniques is the limited resolution. Currently, there are two ongoing research projects regarding detector development for imaging and quality assurance in radiotherapy.
