In radiotherapy one aims to deliver a radiation dose to a tumour with high geometrical accuracy while sparing organs at risk (OARs). Although image guidance decreases geometrical uncertainties, treatment of cancer of abdominal organs is further complicated by respiratory motion, requiring intra-fraction motion compensation to fulfil the treatment intent. With an ideal delivery system, the optimal method of intra-fraction motion compensation is to adapt the beam collimation to the moving target… CONTINUE READING
