摘要：
Systems and methods for generating imaging biomarkers that indicate detectability or conspicuity of lesions that may be present in mammographic images are provided. In general, a task-based measure of a signal-to-noise ratio (“SNR”) measurement of a detection task is computed over a number of small regions-of-interest (“ROIs”) in an image, and the computed parameter is used to predict what detection rates should be if a lesion was present in the image. As such, the computed parameter can be used to define an imaging biomarker that is a “masking measure” that indicates the degree of conspicuity of lesions that may be present in a given a mammographic image.
