A new technique to systematically minimize misregistration introduced errors in cardiac perfusion studies with attenuation correction

Abstract

In cardiac perfusion studies (both PET and SPECT) with CT-based attenuation correction, intensive efforts have been made to minimize the emission/transmission misregistration in order to minimize the errors introduced by the misregistration in the attenuation corrected images. In this work, we propose a new technique to systematically minimize the errors… (More)
