“…As a consequence of the current digital revolution, traditional film-based hospitals are converting to digital hospitals, where patient medical records, chart information, and test results are easily available electronically for physicians from anywhere in the hospital and beyond. As such, full-digital mammography is gaining importance compared to conventional film-screen mammography due to the possibility of separating and individually optimising digital acquisition, digital storage, and digital display [1][2][3].…”

Digital mammograms may present an overexposed area in the peripheral part of the breast, which is visually shown as a darker area with lower contrast. This has a direct impact on image quality and affects image visualisation and assessment. This paper presents an automatic method to enhance the overexposed peripheral breast area providing a more homogeneous and improved view of the whole mammogram. The method automatically restores the overexposed area by equalising the image using information from the intensity of non-overexposed neighbour pixels. The correction is based on a multiplicative model and on the computation of the distance map from the breast boundary. A total of 334 digital mammograms were used for evaluation. Mammograms before and after enhancement were evaluated by an expert using visual comparison. In 90.42% of the cases, the enhancement obtained improved visualisation compared to the original image in terms of contrast and detail. Moreover, results show that lesions found in the peripheral area after enhancement presented a more homogeneous intensity distribution. Hence, peripheral enhancement is shown to improve visualisation and will play a role in further development of CAD systems in mammography.

“…These ratios typically range from 1.5 to 3:1, and so only moderate savings in storage space are realized. Lossy compression ratios higher than 3 or 4:1 are currently not recommended, mainly due to concerns about the possible inability to evaluate subtle calcifications at these higher ratios (21). To date, several studies have shown that compression ratios far higher (as far as 80:1) might not result in loss of diagnostic information (22)(23)(24).…”
