Abstract
A method for reconstructing a radioactive emission image of an overall volume having first and second volumetric regions, each volumetric region having respectively independent dynamic characteristics. The method comprises the following steps: a) obtaining radioactive emissions from the overall volume, including the volumetric regions, b) reconstructing an initial radioactive emission image of the volumetric region according to the radioactive emissions, c) segmenting the initial radioactive emission image to delineate the first and second volumetric regions, and d) separately reconstructing the first and the second volumetric regions according to the respectively independent dynamic characteristics.
