摘要： A medical X-ray tomographing apparatus, wherein the output end surfaces of a plurality of optical fiber bundles are optically coupled to the image pickup surfaces of vertically long solid-state image pickup devices, such as one-dimensional image sensors, and the input end surfaces of a plurality of the optical fiber bundles having a vertically long cross-sectional shape being identical to that of the output end surfaces thereof are optically coupled individually to a plurality of vertically long divisions obtained by dividing the fluorescent surface of a scintillator in the width direction thereof. With this apparatus, it is not necessary to significantly contract the size of the image on the fluorescent surface, thereby remarkably reducing the number of the solid-state image pickup devices and the number of the divisions of the fluorescent surface.
