Abstract:
Method for calibrating a detector means intended for use in an apparatus for radiotherapy, characterised in that it comprises the steps of:placing a patient in the radiotherapy apparatus with the part of the patient to be treated between a radiation emitting device and the detector means,applying a number of first detectors on the patient,radiating the patient and the first detectors with a beam,measuring the emitted radiation with the first detectors in order to quantify the radiation dose,detecting the radiation emitted and passed through the patient with the detector means, the detector means comprising a plurality of second radiation detectors arranged as to detect the radiation beam,determining the value of the detected radiation from the second detectors of the detector means, andrelating the value of the detecting means with the measured radiation dose, thereby quantifying the radiation detected by the detector means.
