Abstract:
1. An X-ray CT apparatus for obtaining a cross-section image or a 3D image of an inside of a sample with X-rays, comprising: an X-ray generating apparatus, which is configured to irradiate the X-rays on the sample; an X-ray detecting device, which is configured to detect the X-rays passing through the sample; and a device, which is configured to process a detection signal from the X-ray detecting device and obtain the cross-section image or the 3D image of the inside of the sample; a gantry including an X-ray shield having an opening portion at one end to introduce the sample therein and treated with an X-ray protection process on an entire periphery thereof; a motor to drive rotation of the X-ray shield around a rotational axis; and a sample setting portion attached to the gantry around the opening portion of the X-ray shield, wherein: the sample setting portion has an outer peripheral wall formed with the X-ray shield, a part movable to open and close, and a to plate to move the sample into an inside of the X-ray shield, the X-ray generating apparatus and the X-ray detecting device are respectively treated with the X-ray protection process, are fixed on a wall surface of the X-ray shield at positions opposing each other with the rotational axis therebetween, and constructed with the X-ray shield in one body.
