Objective comparison of high‐contrast spatial resolution and low‐contrast detectability for various clinical protocols on multiple CT scanners

Purpose We sought to compare objectively computed tomography (CT) scanner performance for three clinically relevant protocols using a task‐based image quality assessment method in order to assess the potential for radiation dose reduction. Methods Four CT scanners released between 2003 and 2007 by d...
