To perform temperature control of a detector module unit by a simple method.SOLUTION: An X-ray CT apparatus comprises: a detector unit; an acquisition unit; an air blower unit; an opening/closing mechanism; and an opening/closing control unit. The detector unit includes a plurality of detector modules which are arrayed in the channel direction and a housing which is provided in the periphery of the plurality of detector modules. The acquisition unit acquires information about a heat quantity in the detector module. The air blower unit is provided in at least one of a suction port and an exhaust port respectively provided on two faces in the column direction of the housing. The opening/closing mechanism is provided between the suction port of the housing and the detector module or between the exhaust port of the housing and the detector module. The opening/closing control unit controls the opening/closing mechanism on the basis of information.SELECTED DRAWING: Figure 2 【課題】簡易な方法で検出器モジュール単位の温度制御を行うこと。【解決手段】実施形態に係るＸ線ＣＴ装置は、検出器ユニットと、取得部と、送風部と、開閉機構と、開閉制御部とを備える。検出器ユニットは、チャンネル方向に配列された複数の検出器モジュールと、複数の検出器モジュールの周囲に設けられる筐体とを含む。取得部は、検出器モジュールにおける発熱量に関する情報を取得する。送風部は、筐体の列方向の２面にそれぞれ設けられる吸気口及び排気口の少なくとも一方に設けられる。開閉機構は、筐体の吸気口と検出器モジュールとの間、又は、筐体の排気口と検出器モジュールとの間に設けられる。開閉制御部は、情報に基づいて開閉機構を制御する。【選択図】 図２
