Abstract
A radiation detector () includes a two-dimensional array of upper scintillators (τ) which is disposed facing an x-ray source () to convert lower energy radiation into visible light and transmit higher energy radiation. A two-dimensional array of lower scintillators (B) is disposed adjacent the upper scintillators (τ) distally from the x-ray source () to convert the transmitted higher energy radiation into visible light. Respective active areas () of each upper and lower photodetector arrays (B) are optically coupled to the respective upper and lower scintillators (B) at an inner side () of the scintillators (B) which inner side () is generally perpendicular to an axial direction (Z). Interference filters () may be deposited on the active areas () of the associated upper and lower photodetectors (B) to restrict radiation wavelengths received by the upper and lower photodetectors (B) to wavelengths emitted by the respective upper and lower scintillators (B). The upper scintillators (τ) may include at least one of ZnSe(Te) and YAG(Ce).
