PROBLEM TO BE SOLVED: To give a sense of security to a subject and reduce a mental burden on the subject by efficiently sending air to an imaging space at a temperature corresponding to a temperature in the imaging space and an imaging condition.SOLUTION: A magnetic resonance imaging device includes a gantry having an imaging space where a subject is placed, and an air outlet for air to be sent to the imaging space, an air blower for supplying air to be sent to the imaging space, air-conditioning equipment for generating cool air to be supplied to the air blower, an air-conditioning control part for controlling an operation of the air-conditioning equipment, a temperature sensor for acquiring information on a temperature in the imaging space, and a target temperature input part for inputting a target temperature. The air-conditioning control part controls the temperature of the cool air generated by the air-conditioning equipment based on the target temperature, the temperature information from the temperature sensor, and an imaging condition for imaging the subject.SELECTED DRAWING: Figure 2【課題】 撮像空間の温度と撮像条件とに対応した温度で撮像空間へ効率的に送風することで、被検者への安心感と精神的負担の軽減を行う。【解決手段】 被検者が配置される撮像空間と、撮像空間へ送風する空気の送風口とを備えたガントリと、撮像空間へ送風する空気を供給する送風機と、送風機に供給する冷風を生成する空調設備と、空調設備の動作を制御する空調制御部と、記撮像空間の温度情報を取得する温度センサと、目標温度を入力する目標温度入力部と、を備え、空調制御部は、目標温度と、温度センサからの温度情報と、 被験者を撮像するための撮像条件とに基づいて、空調設備が生成する冷風の温度を制御する。【選択図】 図2
