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.
Claims11
A method for visual assessment of a phantom image, comprising the steps of:
- registering a digital image to a phantom template to generate a plurality of individual targets;
- sequentially displaying each individual target to a user for visual assessment;
- allowing display control adjustment of the displayed individual target;
- and
- allowing the user to indicate at least one assessment of the displayed individual target.
A method for human visual reading of image data for image quality assessment, comprising the steps of:
- registering a digital image to a phantom template to generate a plurality of individual targets;
- determining characteristics of the digital image corresponding to each of the plurality of individual targets;
- sequentially displaying each individual target to a user based on the determined characteristics;
- allowing display control adjustment of the displayed individual target;
- and
- allowing a user to indicate at least one assessment of the displayed individual target.
