Abstract
An arithmetic procedure was developed to determine the radioactivity r equired for an attenuation-correction transmission source for the deli very of a predetermined patient radiation dose for various patient-sou rce configurations. The procedure determines the absorbed energy per i ncident photon from a chosen transmission radionuclide, based on Monte Carlo data. Results were verified using TLD and ionization chamber me asurements. The method is useful in calculating the transmission sourc e radioactivity for transmission computed tomography using a two-dimen sional transmission source.
