Abstract

This communication is the result of an NIH SBIR Phase 1 project under way because of the concern for wide spread breast-cancer [1,2]. The primary goal of the project is to increase the detection rate of micro calcifications by decreasing spatial noise of the LCD used to display the mammograms [3,4]. Noise reduction will be done with a sensitive CCD Camera and application of Error Diffusion [5,6]. This procedure is known to reduce threshold contrast of human observers [7]. A second goal is the detection of breast cancer using mammogram patches with a pixel matrix of 256 x 256 pixels. Detection of breast cancer will be done using two methods: One is a conventional ROC study [8]. The other is a Vision Model developed over several years, starting at the Sarnoff Research Center and continuing at Siemens Corporate Research in Princeton NJ [9].
