Fisher information analysis of list-mode SPECT emission data for joint estimation of activity and attenuation distribution
Md Ashequr Rahman, Yansong Zhu, Eric Clarkson +3
The potential to perform attenuation and scatter compensation (ASC) in single-photon emission computed tomography (SPECT) imaging using only the SPECT emission data is highly signi…
