Digital mammography: from planar imaging to tomosynthesis
Early investigations on the physical properties of digital mammography provided the impetus for further research [11-15]. These studies suggested that the image noise characteristics of digital systems could be better than for screenfi lm mammography. Therefore, the highresolution advantage of screen fi lm might not be as important for detection of microcalcifi cations in the breast as it was o...
متن کاملSingle Photon 2 { D Imaging System Prototype forBiopsy Digital Mammography
We have developed a digital radiography system based on double sided mi-crostrip silicon crystals. The detector is 300 m thick, equipped with 320 channels for each side. The strip pitch is 100 m. The read{out system consists of a VLSI integrated analog circuit with low noise preampliication, pulse shaping, threshold discrimination. The two main issues of this Front End chip are low noise and go...
متن کاملThe Digital Database for Screening Mammography
The Digital Database for Screening Mammography (DDSM) is a database of digitized film-screen mammograms with associated ground truth and other information. The purpose of this resource is to provide a large set of mammograms in a digital format that may be used by researchers to evaluate and compare the performance of computer-aided detection (CAD) algorithms. The database was completed in the ...
متن کاملComparison of digital mammography alone and digital mammography plus tomosynthesis in a population-based screening program.
PURPOSE To assess cancer detection rates, false-positive rates before arbitration, positive predictive values for women recalled after arbitration, and the type of cancers detected with use of digital mammography alone and combined with tomosynthesis in a large prospective screening trial. MATERIALS AND METHODS A prospective, reader- and modality-balanced screening study of participants under...
متن کاملDigital mammography.
Digital mammography is an irreversible evolution which will gradually replace analog mammography. Detector technology differs among manufacturers. Expected clinical advantages are improved diagnostic performances, improved reproducibility, dose reduction, dedicated applications (CAD), archiving and telemammography. Limiting problems are at cost, reorganization of the breast imaging unit and the...
