The quantitative and visual interpretation of SPECT myocardial perfusion images is limited
by physical factors such as photon attenuation, Compton scatter, and finite resolution effects …

Photon attenuation in cardiac single photon emission computed tomography (SPECT) is a
major factor contributing to the quantitative inaccuracy and the decrease in specificity of …

Simultaneous correction of nonuniform attenuation and detector response was implemented
