Abstract

The conspicuity of a mass represents a ratio between the contrast of a mass and its surrounding complexity. Measuring the conspicuity of lesions attempts to characterise the visibility of a lesion in terms of the imaging systems diagnostic capabilities, and the lesion structure within the tissue surrounding it. Our recent study demonstrates a negative impact of motion on lesion detection performance in full-filed digital mammography (FFDM) using blurring software to apply simulated motion blur on FFDM images containing malignant masses. Within this current study, we have used a new software programme and associated Excel spread sheet to perform physical measures of the expected visual detectability of focal breast lesions (masses). The purpose of this is to identify physical parameters, such as lesion conspicuity, image noise, and lesion edge angle and the relationship they have with detection in the presence of different magnitudes of simulated motion blur (Figure 1).
