Conspicuity Index – a novel method for assessing lesion visibility in DICOM images

A novel method has been developed to provide an objective measure of the visual detectability of focal abnormalities within DICOM images.

ROIs are utilised and fits the lesion using least squares. 180 line-profiles are plotted around the lesion.

An algorithm has been developed that considers the lesion size, edge angle, the internal lesion noise, the surrounding tissue noise and the grey level difference between the background and the lesion.
