Abstract
A method is provided for monitoring and/or signalling errors of a radiation therapy apparatus during delivery of a radiation treatment to a target, the radiation therapy apparatus being configurable for a given radiation treatment by means of a beam shaping device. The method includes providing a radiation array detector between the beam shaping device and the target, capable of providing a measured detector response of the radiation treatment; determining a predicted detector response for successive times of the radiation treatment; measuring the measured detector response caused by the radiation beams for corresponding successive times of the radiation treatment; performing a comparison between the measured detector response and the corresponding predicted detector response; signalling in a short reaction time, an error when the comparison results in a difference which exceeds a given threshold. The disclosure also relates to a device comprising electronic 2-dimensional detectors, processor device and a main software.
