Abstract
A method for image quality assessment of a digital radiography system extracts and isolates one or more individual targets from a phantom image, then obtains operator responses by displaying each isolated individual target and recording a corresponding operator response related to image appearance for each isolated individual target. The accumulated operator responses are stored to obtain the image quality assessment.
