Correlation between a 2D channelized Hotelling observer and human observers in a low‐contrast detection task with multislice reading in <scp>CT</scp>

Abstract

A 2D CHO model is highly correlated with human observer performance in detecting spherical low contrast objects in multislice viewing of CT images. This finding provides some evidence for the use of a simpler, 2D CHO to assess image quality in clinically relevant CT tasks where multislice viewing is used.
