Abstract
A computerized method to aid in human visual reading of phantom image data for task-based image quality assessment. A digital image is registered to a phantom template to generate a plurality of individual targets. The individual targets are sequentially displayed to a user for visual assessment. A display control adjustment is provided for each of the displayed individual targets. The user then indicates at least one assessment of the displayed individual target, and the assessments for all the plurality of targets is stored for analysis. In one arrangement, the individual targets are randomly rotated prior to being sequentially displayed.
