Nonlinear dual reconstruction of SPECT activity and attenuation images.

Nonlinear dual reconstruction of SPECT activity and attenuation images.

In single photon emission computed tomography (SPECT), accurate attenuation maps are needed to perform essential attenuation compensation for high quality radioactivity estimation. Formulating the SPECT activity and attenuation reconstruction tasks as coupled signal estimation and system parameter i...
