Abstract
Flat panel detectors (FPDs) with two separate scintillator layers enable dual-energy (DE) 2D and 3D x-ray imaging with perfect temporal registration. A thick (1 mm) Cu layer is permanently sandwiched between the two scintillators to widen the spectral separation. Because the majority of clinical applications of FPDs do not benefit from DE imaging, the existence of the Cu layer during those applications degrades the overall dose efficiency. In this work, a novel dual-layer FPD design with a removable liquid filter design was presented to improve the dose efficiency of dual-layer FPDs when they are used for non-DE imaging applications.
