つことを特徴とするリング型ＥＣＴ装置。 A cylindrical light guide is fixed at a position corresponding to the hole between the front wall and the rear wall that have holes that define the inspection area, and a rod-shaped scintillator that is long in the axial direction is attached to the inner peripheral surface of the light guide. In a ring-type ECT device in which a large number of photomalles are arranged adjacent to each other in the direction and are arranged radially on the outer circumferential surface of the light guide, the light guide has a plurality of photomultipliers arranged on the inner circumferential surface of one end of the light guide in a part of the inner circumferential surface of the one end that avoids the scintillator. A ring-shaped ECT device characterized by having a tapered ridge that becomes higher as it goes outward in the axial direction.
