ABSTRACT:
An X-ray CT scanner has a gantry incorporating a stator and a rotator therein. In the gantry, there is provided an optical transmission system for transmitting a light signal concerning the X-ray scan between both the stator and rotator that are opposed to each other in an axial direction of a opening of the gantry in a non-contact state. In the optical transmission system, there are provided a plurality of light emitting elements for emitting the light signal, a light receiving element for receiving the light signal, and a light collector for converging the light signal onto the light receiving element. Each of light emitting elements is equidistantly mounted on a side of the rotator faced to the stator, and the light receiving element is mounted on a side of the stator faced to the rotator, and a light collector is joined with the light receiving element. The light collector is an cone-like member having an aperture for taking in the light signal at one side thereof and a bottom at another side thereof. One side is faced to the another side and the light receiving element is mounted on the bottom. The cone-like member has a mirror-finished inner wall surface and a white-colored inner wall surface.
