    摘要： An optical mask layer for a CT detector is disclosed and is disposed between the photodiode array and scintillator array of a CT detector. The optical mask layer, which may extend along the x-axis, z-axis, or both, is designed to absorb and/or reflect light emitted the scintillators of the scintillator array. Through this absorption and/or reflection, transference of light photons from a scintillator to the photodiode corresponding to a neighboring scintillator is reduced. This reduction in cross-talk reduces artifacts in a reconstructed image and therefore improves the diagnostic value of the image.

    摘要： A CT system is disclosed that includes detector modules positioned on a rotatable gantry configured to receive x-rays attenuated by an object. Each detector module includes a module frame, a plurality of tileable sub-modules on the module frame aligned along a Z-axis thereof to receive the x-rays attenuated by the object and convert the x-rays to digital signals, and an electronics board connected to the plurality of sub-modules to receive the digital signals. Each sub-module further includes an array of detector elements to receive x-rays attenuated through the object and convert the x-rays into analog electrical signals, an ASIC electronics package coupled to the array of detector elements to receive the analog electrical signals and convert the analog electrical signals to digital signals, and a flex circuit connected to the ASIC electronics package to receive the digital signals and transfer the digital signals to the electronics board.
