    摘要： The present invention relates to a method for monitoring and/or signalling errors of a radiation therapy apparatus during delivery of a radiation treatment to a target, said radiation therapy apparatus being configurable for a given radiation treatment by means of a beam shaping device (MLC), the method comprising the steps of: - providing a radiation transparent array detector (T2D) between said beam shaping device (MLC) and said target, capable of providing a measured detector response (70) of said radiation treatment; - determining a predicted detector response (60) for successive times of said radiation treatment; - measuring said measured detector response (70) caused by the radiation beams for corresponding successive times of said radiation treatment; - performing a comparison (S300) between the measured detector response (70) and the corresponding predicted detector response (60); - signalling in a short reaction time, an error (S400) when said comparison results in a difference which exceeds a given threshold. The present invention also relates to a device comprising electronic 2-dimensional detectors, processing means and a main software (MS).

    摘要： 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.
