X-ray CT apparatus

An X-ray CT apparatus including

• an X-ray imaging system including an X-ray irradiation unit and an X-ray detector,
• a stage disposed between the X-ray irradiation unit and the X-ray detector,
• a rotation mechanism configured to relatively rotate the X-ray imaging system and the stage about a rotation axis orthogonal to an optical axis of an X-ray that runs from the X-ray irradiation unit to the X-ray detector, and
• a load mechanism which is set on the stage and is configured to apply test force to a test piece,
• the X-ray CT apparatus comprising:
• an angle changing mechanism configured to tilt the load mechanism to change a direction of the test force applied to the test piece by the load mechanism from a direction orthogonal to the optical axis of the X-ray;
• a camera configured to take a picture of the test piece;
• and
• a connection member connecting the load mechanism to the camera so that the camera tilts together with the load mechanism.
