PROBLEM TO BE SOLVED: To provide an X-ray CT apparatus capable of easily coping with the adjustment and replacement of various devices in a short time and stabilizing electric signals and mechanical rotation.SOLUTION: The X-ray CT apparatus includes: a bed where a patient is to be put on a rack rotating body rotated around the bed and having a plurality of openings communicating with an inner peripheral part and an outer peripheral part an X-ray radiation part mounted on the inner peripheral part of the rack rotating body an X-ray detection part disposed on the inner peripheral part of the rack rotating body facing the X-ray radiation part, for detecting X-rays which are radiated from the X-ray radiation part and transmitted through the patient and a power supply part provided outside the rack rotating body, for supplying power to the X-ray detection part and the X-ray radiation part. A feeder connecting the power supply part and the X-ray radiation part and the X-ray detection part is disposed at the outer peripheral part of the rack rotating body, and connected to the X-ray radiation part and the X-ray detection part respectively through the openings provided on the positions near the X-ray radiation part and the X-ray detection part respectively.COPYRIGHT: (C)2011,JPO&INPIT【課題】 各装置の調整や交換作業が容易に短時間で対応できると共に、電気信号及び機構的回転の安定を図ることが可能なX線CT装置を提供すること。【解決手段】患者が載置される寝台と、この寝台の周りに回転し、内周部及び外周部に通ずる複数の開口部を有する架台回転体と、この架台回転体の前記内周部に設置されるX線放射部と、このX線放射部に対向して前記架台回転体の前記内周部に設置され、前記X線放射部から放射され前記患者を透過したX線を検出するX線検出部と、前記架台回転体の外に設けられ前記X線検出部及び前記X線放射部へ電力を供給する電力供給部と、を備え、前記電力供給部と前記X線放射部及び前記X線検出部を接続する給電線は、前記架台回転体の外周部に配設され、前記X線放射部及び前記X線検出部各々に近い位置に設けられた前記開口部を通して、前記X線放射部及び前記X線検出部各々に接続されることを特徴するX線CT装置。【選択図】図1
