The preliminary work described above defined the data size needed for proper digital mammography, the necessary methods for image processing and requirements for display. These are essential components for making digital mammography MDIS compatible. One can duplicate the lesion detectability of screen films mammograms in phantoms with a 100 micron pixel with 2 by 2.5 K for an 8 by 10 image. A 2 by 2.5 K image can be displayed on the higher resolution MDIS monitors. 2 by 2.5 K images are comparable in size with chest images and therefore should be able to be stored in the image data base. The performance features for MDIS compatible workstation has been defined, in collaboration with a MDIS radiologist and they will be implemented and tested in year 2. We have defined the data set size needed for digital mammography. This is fundamental work for understanding and development methods for telemammography. Our preliminary tests of fim scanners indicate that 100 microns may be acceptable, but that smaller pixel sizes may offer some advantages. We will be able to further test film digitization as a method once the Breast cancer, Computer, Mammography, RAD VI.
