[A trial of selective imaging for the breast mass shadow by computed radiography].
CR has ability to make many kinds of images by several imaging processings. Especially, gradation processing is more important than frequency processing to make images in CR mammography. We developed new method to image breast masses selectively with new gradation processing and tried it for 18 patients over sixty years old with breast cancer. All of breast mass shadows were separated selectively from other parenchymal shadow. So, we conclude that the auto-recognition of breast mass shadow can be possible in near future in CR system.
