PROBLEM TO BE SOLVED: To provide an X-ray CT apparatus, capable of preventing a breakage of a bearing.SOLUTION: An apparatus includes: a rotator 26 which holds an X-ray tube 21 for emitting X-ray to a subject P being tested and an X-ray detector 22 for detecting X-ray transmitted by the subject P; a bearing 27 which rotatably supports the rotator 26; a state detection unit 30 which detects a state of the bearing 27; and a determination unit 40 which determines the state of the bearing 27 based on the detection result detected by the state detection unit 30. The state detection unit 30 performs analysis by measuring the sound of the bearing 27, and the determination unit 40 determines that the operation of the bearing is normal when a sound integrated value that is the analysis value of the state detection unit 30 is in a normal value range, and determines that the operation of the bearing is abnormal when the sound integrated value is in a warning value range. |
