                         mammographic images by using Anscombe Transform and Wiener Filter 
                         to quantum noise reduction. Besides, it is performed an image 
                         enhancement by using a restoration inverse filter, calculated 
                         based on the image system modulation transfer function (MTF). This 
                         pre-processing technique were used for a set of mammographic 
                         phantom images in order measure the number of microcalcifications 
                         correctly detected by a computer-aided detection (CAD) algorithm. 
                         Results showedthat the proposed method improved breast images 
                         quality by overcome the acquisition process constrains and 
                         reducing noise. The performance of the breast microcalcification 
                         CAD was improved when using the restored images set in comparison 
                         to the original one.",
