Attenuation correction is required for quantitative analysis in positron emission tomography (PET). At PET energies, the attenuation coefficient may be approximated by the product of the Klein-Nishina cross-section per electron and the electron density. We have evaluated the feasibility of reconstructing the electron density directly from measured PET scatter events in order to obtain the attenuation...
We have proposed a generalized scatter (GS) positron emission tomography (PET) reconstruction algorithm which can extract the activity distribution by using both true and scattered coincidences in a consistent way. However the conventional strategies for attenuation correction are no longer applicable for scattered photons. The goal of this study is to develop a method to address the photon attenuation...
