Contrast detail curves on digital mammography: performance comparison of raw and filtered images

Detection of low contrast and very small size objects is of great importance on digital mammography imaging techniques Hence, when comparing image quality performance for different equipments, it would be desirable to make an objective evaluation primarily based on raw images In this work we present the results of an image quality performance comparison test for digital mammography systems Contrast detail curves obtained for raw and filtered images from a CDMAM v3.4 phantom were analyzed The test resulted in an overall image quality figure index for filtered and raw images of 106.66 and 109.90 respectively for a detection rate threshold of 75% The largest differences were observed with the small diameter dishes of the phantom.
