FIELD: medicine.
SUBSTANCE: group of inventions relates to the external beam radiation therapy. Treatment planning system for generating patient-specific treatment margins contains one or more processors programmed to receive a radiation treatment plan (RTP) for irradiating a target over the course of one or more treatment fractions, wherein said RTP includes one or more treatment margins around the target, and a planned dose distribution, to be delivered to the target, to receive motion data for at least one of the treatment fractions of the RTP, wherein the motion data are received during and/or between the treatment fractions of the RTP, calculate a motion-compensated dose distribution for the target and to compare the motion-compensated dose distribution to the planned dose distribution. Radiation therapy system comprises one or more imaging modalities, planning system, radiation therapy apparatus and a motion monitor generating the motion data from the target surrogates of the targets. Method for generating patient-specific treatment margins comprises the steps of receiving a radiation treatment plan (RTP) for irradiating a target over the course of one or more treatment fractions, wherein RTP includes one or more treatment margins around the target and a planned dose distribution for the target, receiving motion data for at least one of the treatment fractions of the RTP, calculating a motion-compensated dose distribution for the target and comparing the motion-compensated dose distribution to the planned dose distribution. By the second version a radiation therapy system comprises a radiation therapy apparatus, motion monitor generating motion data from target surrogates of a target and one or more processors programmed to perform the method.
EFFECT: using the group of inventions makes it possible to consider the resultant effect of motion for determined zone.
