Statistical model based iterative reconstruction (MBIR) in clinical CT systems. PartII. Experimental assessment of spatial resolution performance

摘要

Purpose:Statistical model based iterative reconstruction (MBIR) methods have been introduced to clinical CT systems and are being used in some clinical diagnostic applications. The purpose of this paper is to experimentally assess the unique spatial resolution characteristics of this nonlinear reconstruction method and identify its potential impact on the detectabilities and the associated radiation dose levels for specific imaging tasks.
