| 摘要 |
<p>The present invention relates to a 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 detectors on the patient, radiating the patient and the detectors, measuring the emitted radiation with the detectors in order to quantify the radiation dose, detecting the radiation emitted and passed through the patient by the detector means, whereby the detector means comprises a plurality of radiation detectors arranged as to detect the radiation beam, determining the value of the detected radiation from the detectors of the detector means, and relating the value of the detecting means with the measured radiation dose, thereby quantifying the radiation detected by the detector means. <IMAGE></p> |
