Attenuation correction for a generalized scatter reconstruction in PET

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 applicab...

Summary: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 However the conventional strategies for attenuation correction are no longer applicable for scattered photons.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 correction for scattered coincidences.
