PURPOSE With on-line portal imaging devices and image registration tools, the verification of radiation field position prior to each treatment becomes technically feasible. In this paper, we analyze the impact of pre-treatment verification and field position adjustment on target coverage and normal tissue sparing. METHODS AND MATERIALS Port films were compared with corresponding simulation films to determine the magnitude of setup variations in patients treated for prostate cancer. From these… CONTINUE READING
