Development of High-sensitivity and High-resolution Digital Mammography System ‘AMULET’

FUJIFILM’s newly-developed ‘AMULET’, a digital mammography system, simultaneously realizes high-image quality, low-dose image acquisition and high-throughput as well as patient-oriented design. A detector mounted on AMULET directly converts X-ray signals into electronic signals to readout the electronic signals by using a uniquely developed “Direct Optical Switching” readout method in its imaging process. This detector with dual amorphous Se layers makes it possible to deliver high-definition diagnostic images consisting of 50 μm-size pixels providing the finest resolution among direct-conversion X-ray image detectors. Well-optimized Auto-Exposure-Control between the direct-conversion detector and an x-ray tube with Mo and W targets can meet the wide range of diagnostic needs from high-image quality to low-dose exposure. Moreover, ergonomic design helps to alleviate patient’s discomfort.
