Abstract

In this paper, two new selenium large area detectors are introduced. The first detector is a 24x30cm detector suitable for full-field digital mammography applications. The second detector is a new 43x43cm detector for general radiographic applications. Both detectors are capable of static and dynamic imaging, and are quantum noise limited over the exposure ranges intended for their typical use. For static imaging applications, ghost and lag were compared on both detectors, and no measurable artefacts were reported. On dynamic imaging sequences, lag was shown to be significant on both detectors, and a method for reducing the artifact due to lag was presented.
