摘要： To realize an X-ray detector and an X-ray CT apparatus with improved efficiency for X-ray utilization while leaving gaps existing among solid state detectors which are arranged two-dimensionally. A scintillator has a parallelepiped structure in which a top face and an under face are deviated from each other in a channel direction only by an amount d1 exceeding width of a gap, thereby eliminating an X-ray insensitive area when viewed from the X-ray incidence direction. Therefore, efficiency for X-ray utilization improves and, moreover, improvement in X-ray detectivity and picture quality of a slice image to be captured is realized.
