A High Resolution Scanning Slot X-Ray Imaging Detector for Digital Mammography.
Abstract
There has been a major modification of the contents of the proposed work. The objective of this reported research is to develop new screen-film combinations which provide improved breast lesion and microcalcification sensitivity in dense fibroglandular tissue without compromising diagnostic sensitivity for the "average"? breasts. The essential novelty of the approach lies in recognizing that 50% of the light produced in the phosphor screen is wasted in the current mammography screen-film technology. The proposed approach uses that light by exposing a second film which has similar film contrast, but, is faster than the first film, thereby permitting a wider exposure latitude imaging system without compromising image contrast. Two prototype screen-film combinations were developed. The test results demonstrated that, in addition to producing a breast image which is equivalent to the conventional screen-film method, the second film could provide enhanced diagnostic information for dense breast areas which are underexposed on the first film. The proposed technique could be the dominant approach to improve mammography in small hospitals for the next decade and provide cost-effective health care in the rural areas.
