“…Prior to display CR image data is manipulated using a proprietary (Fuji, Tokyo, Japan) digital image processing environment [3]. Several user groups have identified deficiencies in the "default" digital image processing applied by the CR to mammographic image data [8,9,14,15]. Concerns focus on the sub-optimum rendition of micro-calcifications and low-contrast masses which impacted heavily on the diagnostic acceptability of CM.…”

“…This problem has amplified users' concerns regarding the apparent lack of spatial resolution of CM and may have contributed to the early disappointing reports. Freedman et al have confirmed that when the parameters of the image processing algorithm are optimized, the detectability of simulated micro-calcifications in CM and SFM become equivalent [15]. At Leeds a complete solution to the image processing problem had to await the development and implementation of an entirely different image processing environment on the CR system.…”

Mammography is a branch of radiology which could benefit greatly from the assimilation of digital imaging technologies. Computerized enhancement techniques could be used to ensure optimum presentation of all clinical images. Beyond this it will facilitate powerful new clinical resources such as computer-assisted diagnosis, tele-mammography, plus digital image management and archiving. An essential precursor to all these advances is the availability of appropriate direct digital mammography (DDM) image-acquisition system(s) to capture high-quality breast X-ray image data at the outset. The only practical DDM image-acquisition system currently available is (photo-stimulable phosphor) computed radiography. Modern computed mammography (CM) uses similar radiation doses to the patient and produces equivalent, albeit different, image quality to screen-film mammography. Computed mammography offers superior rendition of the skin edge and sub-cutaneous tissue and dense parenchyma, while ensuring equivalent micro-calcification detectability. Meanwhile, a variety of new technical approaches to DDM are under active investigation and/or development which promise to supercede film-based mammography. These new (second generation) DDM technologies promise the radiologist superior image quality combined with significant dose savings compared with contemporary imaging systems. In this review we describe and compare the physical and clinical characteristics of CM and the various emerging DDM image-acquisition technologies.

“…if one looks at reports summarizing the image characteristics of cancers missed on screening mammography, many of them occur in regions of increased breast radiodensity (Farria, Bird, Harvey, Silverstein). Our previous reports to SPIE Medical Imaging (Freedman, 1994 and reported that digital mammography had a wider range of effective exposures than did screen film mammography, as summarized in the following chart: 1: This chart demonstrates the smallest sized test details visible on the CIRS Detail Phantom as exposure is varied, comparing two systems: conventional screen film mammography and Fuji Digital Storage Phosphor radiography, processed in Sensitivity Mode. At low exposure levels, the digital system allows the detection of simulated microcalcifications that cannot be seen in the conventional system.…”

The sensitivity of mammography for the detection of breast cancer is decreased in the radiodense breast. Storage phosphor digital radiographic systems have a wider latitude of exposure than conventional mammographic screen film systems. By using low resolution histogram equalization one can produce a mammographic image of the breast that retains the high frequency information that defines the edges of microcalcifications, architectural distortion and some masses but which, at the same time, allows one to look through into regions of increased breast radiodensity and identify microcalcifications within them. This paper demonstrates the effect of this special form of image processing.
