Direct Reconstruction of CT-based Attenuation Correction Images for PET with Cluster-Based Penalties
Extremely low-dose CT acquisitions for the purpose of PET attenuation correction will have a high level of noise and biasing artifacts due to factors such as photon starvation. This work explores a priori knowledge appropriate for CT iterative image reconstruction for PET attenuation correction. We...
