Abstract :
Anatomical information derived from x-ray and NMR tomographic sections is useful for producing more accurate reconstructions of radioactivity distributions in the same section from emission-tomography data. Additionally, attenuation information acquired for calibration in emission tomography is necessary for producing accurate reconstructions of activity. An algorithm based on the maximum-likelihood method of statistics is identified for utilizing both of these forms of side information in emission-tomography systems.
