X-ray detector, x-ray detector module, and x-ray ct apparatus

An X-ray detector module comprising:

• a detection surface on which a plurality of detection elements configured to detect X-rays are arrayed;
• and
• a supporter configured to support the detection elements, wherein
• a pin protruding toward the supporter is provided to a frame configured to fix a position of the X-ray detector module, at a position to which the supporter is fixed,
• the supporter has a hole through which and with which the pin is inserted and fitted, at a position facing the frame, and
• a movement of the supporter in a direction in which the X-ray detector module are arranged in plurality is restricted by fitting the pin provided to the frame into the hole provided to the supporter, when the supporter is attached to the frame.

An X-ray CT apparatus comprising:

• an X-ray tube configured to emit an X-ray;
• and
• a detector configured to detect an X-ray emitted from the X-ray tube and penetrated through a subject, wherein
• the detector comprises:
• a plurality of X-ray detector modules each having a detection surface on which a plurality of detection elements configured to detect X-rays are arrayed, and a supporter configured to support the detection elements;
• and
• a frame configured to fix positions of the X-ray detector modules in such a manner that the detection surfaces of the respective X-ray detector modules are aligned along a first direction, wherein
• the frame is provided with a pin protruding toward the supporter, at a position to which the supporter is fixed,
• the supporter is provided with a hole through which and into which the pin is inserted and fitted, at a position facing the frame, and
• a movement of the supporter in the first direction is restricted by fitting the pin provided to the frame into the hole provided to the supporter, when the supporter is attached to the frame.
