A revised model of the kidney for medical internal radiation dose calculations
Presently, there is a need for a revised model for the kidneys which clearly distinguishes major regions and structures in the kidneys. This model is needed since radionuclides used currently in nuclear medicine have marked preferences for various regions of the kidneys, and the radiation dose to one or more of these regions is of primary importance. At this time the kidneys are modeled as solid organs of uniform density by the ALGAM computer code, which uses Monte Carlo techniques to calculate absorbed fractions. This presentation will introduce a model in which the source regions will be the cortex, medulla and the papillae, while the target regions will be these regions as well as the other organs of the body. This research presents for the first time estimates of the specific absorbed fractions in various organs of the body from a source in the specific region of the kidneys. 17 refs., 8 figs., 10 tabs.
