- W2062864629 abstract "This presentation describes work in progress that is the result of an NIH SBIR Phase 1 project thataddresses the wide- spread concern for the large number of breast-cancers and cancer victims [1,2].The primary goal of the project is to increase the detection rate of microcalcifications as a result ofthe decrease of spatial noise of the LCDs used to display the mammograms [3,4]. Noise reduction isto be accomplished with the aid of a high performance CCD camera and subsequent application oflocal-mean equalization and error diffusion [5,6]. A second goal of the project is the actual detectionof breast cancer. Contrary to the approach to mammography, where the mammograms typically havea pixel matrix of approximately 1900 x 2300 pixels, otherwise known as FFDM or Full-Field DigitalMammograms, we will only use sections of mammograms with a pixel matrix of 256 x 256 pixels.This is because at this time, reduction of spatial noise on an LCD can only be done on relativelysmall areas like 256 x 256 pixels. In addition, judging the efficacy for detection of breast cancer willbe done using two methods: One is a conventional ROC study [7], the other is a vision modeldeveloped over several years starting at the Sarnoff Research Center and continuing at the SiemensCorporate Research in Princeton NJ [8]." @default.
