Abstract
Detector module designs for radiographic imaging include first and second layers of scintillator rods or pixel arrays oriented in first and second directions. The first and second directions are transversely oriented to define a light sharing region between the first and second layers. Encoding features may be disposed in, on or between the first and second layers, and configured to modulate propagation of optical signals therealong or therebetween.
Claims15
A detector module comprising:
- a first layer of scintillator elements, each extending in a first direction along the first layer;
- a plurality of photodetectors, including strip photodetectors with a read out at both ends and continuous area photodetectors with a readout at each of the four corners, configured to convert optical signals generated by the scintillator elements into output characterizing radiation interacting therein;
- a second layer of one or more semiconductor detector elements oriented edge on or face on with respect to the radiation;
- and
- an intermediate layer between the first and second layers.
