The present invention relates to a device and method for verification of the quality of a radiation beam in conformal radiation therapy, and in particular for IMRT (Intensity Modulated Radiation Therapy) applications. The actual 3D dose distribution in the patient is tracked during the course of the entire treatment by reconstructing the photon fluences from measured 2D detector responses during irradiation in conjunction with updated patient images.

Device and method for 3D dose tracking in radiation therapy

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.
