PURPOSE To assess carbon ion beam dose variation due to bowel gas movement in pancreatic radiotherapy. METHODS AND MATERIALS Ten pancreatic cancer inpatients were subject to diagnostic contrast-enhanced dynamic helical CT examination under breath-holding conditions, which included multiple-phase dynamic CT with arterial, venous, and delayed phases. The arterial-venous phase and arterial-delayed phase intervals were 35 and 145 s, respectively. A compensating bolus was designed to cover the… CONTINUE READING
