CT DETECTOR

摘要

PROBLEM TO BE SOLVED: To provide a CT detector capable of preventing X-rays from entering gaps between adjacent scintillators in detector modules and preventing X-rays from shifting to adjacent pixels and producing crosstalk.SOLUTION: A CT detector comprises: a detector module that includes multiple scintillators having gaps therebetween and configured for constituting two-dimensional discrete pixels; and a collimator plate located above one side of the detector module receiving X-rays, for guiding the X-rays to the corresponding two-dimensional discrete pixels. The CT detector further comprises grids located between the detector module and the collimator plate, for blocking the X-rays emitted to the gaps.SELECTED DRAWING: Figure 1
