Task-based detectability in CT image reconstruction by filtered backprojection and penalized likelihood estimation
PURPOSE: Nonstationarity is an important aspect of imaging performance in CT and cone-beam CT (CBCT), especially for systems employing iterative reconstruction. This work presents a theoretical framework for both filtered-backprojection (FBP) and penalized-likelihood (PL) reconstruction that include...
