The assessment of the automatic exposure control system for mammography x-ray machine
In the U.S., performance assessment on the Automatic Exposure Control system (AEC) is managed according to the Mammography Quality Standards Act (MQSA). However, The AEC is not available in the performance assessment conducted in Korea. Also, there is no study made on the performance of the automatic exposure control system for mammography in Korea. For this reason, this study examined the perf...
متن کاملAddition of Digital Breast Tomosynthesis to Full-Field Digital Mammography in the Diagnostic Setting: Additional Value and Cancer Detectability
PURPOSE The purpose of this study was to assess the value of adding digital breast tomosynthesis (DBT) to full-field digital mammography (FFDM) in the diagnostic workup of breast cancer and to determine which lesion variables affect cancer detectability in the combined modality. METHODS Between March and May 2012, paired FFDM and DBT images were obtained from 203 women as part of a diagnostic...
متن کاملAutomatic Camera Exposure Control
It is commonplace to use digital video cameras in robotic applications. These cameras have built-in exposure control but they do not have any knowledge of the environment, the lens being used, the important areas of the image and do not always produce optimal image exposure. Therefore, it is desirable and often necessary to control the exposure off the camera. In this paper we present a scheme ...
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...
متن کاملDigital mammography.
IN 1992, A NATIONAL Cancer Institute expert panel determined that, of all emergent technologies, full-field digital mammography (FFDM) held the greatest potential for improving breast cancer detection.1,2 The transition to digital mammography is a necessary step in the ongoing process of improving mammographic image quality and advancing toward the goal of earlier breast cancer detection. Digit...
