Abstract
A method and a calibration system for calibrating a measurement tool for measuring the radiation in a radiation system, such as a radiation therapy system, are provided. The measurement tool, including a holder and at least one photodiode element, is adapted to be mounted in a positioning unit of the radiation system. The radiation sensitive volume of the photodiode element is embedded in a light transparent coating transparent for, for instance, light in the visible spectrum. Thereby, the position of the sensitive volume can easily be determined or calculated with high accuracy relative to the holder on which the photodiode element is arranged, from which the position of the sensitive volume can be determined or calculated in relation to the positioning unit of the radiation system.
