METHOD OF AND SYSTEM FOR DECREASING X-RAY EXPOSURE TIMES IN FULL FIELD DIGITAL MAMMOGRAPHY

摘要

A method of and system for decreasing X-ray exposure time in a full field digital mammography (FFDM) system is designed so that the size of the focal spot image in the image plane is dimensioned as a function of the linear size of the pixel of the digital detector of the detector array and of the geometrical magnification factor of the focal spot so that the modular transfer function is limited only by the pixel size.
