ABSTRACT:
A digital dual-band detector functions as an imaging platform capable of extracting hard and soft tissue images, for example. The detector has a first detector system comprising a first scintillator for converting x-rays from a sample to an first optical signal, and a first detector for detecting the first optical signal in combination with a second detector system comprising a second scintillator for converting x-rays from the sample and passing through the first scintillator to a second optical signal, and a second detector for detecting the second optical signal. The detector can facilitate the implementation and deployment of recent developments and can permit low cost practical deployment in clinical applications as well as biomedical research applications where significant improvement in spatial resolution and image contrast is required.
