Claims (3)

A plurality of scintillator elements arranged in a matrix in a channel direction and a slice direction for converting incident X-rays into light, a photodetector for receiving light emitted from the scintillator elements and converting it into an electrical signal, and the scintillator An X-ray detector for a multi-slice X-ray CT apparatus, comprising: a light shielding means for shielding an optical crosstalk generated between the scintillator elements surrounding a surface other than a surface in contact with the photodetector; An X-ray detector for a multi-slice X-ray CT apparatus, characterized by having a structure. 2. The X-ray detector for a multi-slice X-ray CT apparatus according to claim 1, wherein the multilayer structure includes a light reflecting layer that reflects light emitted from each element of the scintillator, and blocks light transmitted through the light reflecting layer. An X-ray detector for a multi-slice X-ray CT apparatus. An X-ray source and an X-ray detector in which a plurality of scintillator elements are arranged in a matrix in the channel direction and the slice direction are arranged to face each other, and the X-ray source and the X-ray detector are arranged at the same rotation center. The X-ray source weak data of the subject arranged on the rotation center axis is detected by the X-ray detector while being rotated on the circular orbital plane, and the image is reproduced based on the photographed X-ray source weak data. In the multi-slice X-ray CT apparatus capable of obtaining a plurality of slice images of the subject by one rotation of the X-ray source and the X-ray detector around the subject by performing a configuration calculation, line detector multislice X-ray CT apparatus characterized in that it is a multi-slice X-ray CT X-ray detector device of claim 1 or 2.
