Abstract
An MRI study has been performed to determine the respiration induced m otion of the kidneys. Under normal respiration conditions displacement s of the left and right kidney varied from 2 to 24 mm and 4 to 35 mm, respectively. Under forced respiration conditions displacements were l arger and ranged from 10 to 66 mm for the left kidney and 10 to 86 mm for the right kidney. The influence of kidney motion on the radiation dose was determined for patients irradiated on the total abdomen for o varian cancer with shielding of the kidneys during part of the treatme nt. The kidney motion resulted in a larger fraction of the kidney volu me receiving a dose between 20 and 22 Gy.
