Can conclusions drawn from phantom‐based image noise assessments be generalized to in vivo studies for the nonlinear model‐based iterative reconstruction method?

Purpose: Phantom‐based objective image quality assessment methods are widely used in the medical physics community. For a filtered backprojection (FBP) reconstruction‐based linear or quasilinear imaging system, the use of this methodology is well justified. Many key image quality metrics acquired wi...
