METHOD AND DEVICE FOR ONLINE IMRT VERIFICATION |
摘要 |
The present invention relates to a method for monitoring and/or signallin g errors of a radiation therapy apparatus during delivery of a radiation tre atment to a target, said radiation therapy apparatus being configurable for a given radiation treatment by means of a beam shaping device (MLC), the met hod comprising the steps of: - providing a radiation transparent array detec tor (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 r esponse (70) and the corresponding predicted detector response (60); - signa lling 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, processi ng means and a main software (MS).
