1. the irradiation planing method for utilizing particle-irradiation facility (10) to be radiated at the target volume (34,55) of the motion arranged in body (77) by rescanning, has step:

  • Determine (102) target volume in the reference state of motion,Target volume is divided into (103) multiple impact point (30) that can be hit by particle beam individually,Determine (104) multiple rescanning passage, the impact point of the volume that hits the mark respectively in these rescanning passages,Calculate the theoretical dose (58) that (105) will deposit respectively on the impact point of target volume,The expection mean motion (36,50) of the impact point of (106) target volume is calculated by motion model,The expection mean motion of the impact point of target volume is considered like this when irradiating planning, make the deviation of each impact point detection of desired dosage deposition (60) and theoretical dose and based on each impact point of this offset correction theoretical dose and produce the theoretical dose (62) that (107) correctProduce (108) for irradiating the controling parameters of facility, wherein, controling parameters comprises the population will applied each impact point and rescanning passage.
