Abstract

The ultimate aim of radiotherapy is the delivery of correct dose to the patient, which is depends on the correct dose verification before treatment delivery. It is becoming increasingly advantageous to determine the dose from transmission images, whereby the beam passes through the patient. Several studies have addressed reconstruction of dose delivered to the patient during the treatment by means of electronic portal imaging devices (EPIDs).When compared to the traditional EPIDs such as fluoroscopic screen/camera-based and liquid-filled matrix ionization chambers, the new generation of EPIDs, equipped with amorphous silicon (aSi) flat panels, which gives more stable transit signals and are suitable as transit detectors.
