CA 2211080

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 system and method which uses uptake information from the gamma camera images and anatomic data from CT scans. Absorbed dose estimates are obtained by the MAVSK system and method which uses a MCNP to simulate a voxel source kernel for 90Y analogous to a point source function.

L'invention est un système et une méthode servant à déterminer la radioactivité interne et à estimer la dose absorbée par un patient plus exactement et plus facilement. La radioactivité interne est déterminée par le système et la méthode CAMI, lesquels utilisent les informations sur les incorporations fournies par les images de gamma-caméra et les données anatomiques fournies par les tomodensitomètres. Les estimations de dose absorbée sont obtenues au moyen du système et de la méthode MAVSK, lesquels utilisent un MCNP pour simuler un noyau de source de voxels analogue à une fonction de source ponctuelle.
