摘要：
A system and method determines internal radioactivity and absorbed dose estimates of a patient more accurately and with greater ease. Internal radioactivity is determined by the CAMI (CT scan Assisted Matrix Inversion) system and method which uses uptake information from the gamma camera images and anatomic data from CT (Computerized Tomography) scans. Absorbed dose estimates are obtained by the MAVSK (Monte Carlo Assisted Voxel Source Kernel) system and method which uses a MCNP (Monte Carlo program for electron and photon transport) to simulate a voxel source kernel for .sup.90 Y analogous to a point source function.
