MAGNETIC RESONANCE IMAGING APPARATUS AND PROGRAM

To provide a magnetic resonance imaging apparatus and a program capable of detecting, an abnormality in gradient magnetic field coils, without providing a temperature sensor on the gradient magnetic field coil.SOLUTION: A measuring part measures a first temperature representing a temperature of coolant flowing from a cooling device into gradient magnetic field coils and a second temperature representing a temperature of the coolant flowing into the cooling device from the gradient magnetic field coils. The prediction part predicts, as a predicted value, an amount of heat generated by the gradient magnetic field coils when the gradient magnetic field coils are operated on the basis of operating conditions related to operation of the gradient magnetic field coils. The calculation part calculates the amount of heat generated by the gradient magnetic field coils as a measured value on the basis of a temperature difference between the first temperature and the second temperature measured when the gradient magnetic field coils are operated under the operating conditions related to the operation of the gradient magnetic field coils. A determination part determines whether an abnormality has occurred in the gradient magnetic field coils on the basis of a difference value between the predicted value and the actual measurement value.SELECTED DRAWING: Figure 1 【課題】傾斜磁場コイルに温度センサを設けることなく、傾斜磁場コイルの異常を検知することができる磁気共鳴イメージング装置及びプログラムを提供する。【解決手段】計測部は、冷却装置から傾斜磁場コイルに流入する冷媒の温度を示す第１温度及び傾斜磁場コイルから冷却装置に流入する冷媒の温度を示す第２温度を計測する。予測部は、傾斜磁場コイルの動作に係る動作条件に基づいて、傾斜磁場コイルを当該動作条件で動作させた際の傾斜磁場コイルの発熱量を予測値として予測する。演算部は、傾斜磁場コイルを傾斜磁場コイルの動作に係る動作条件で動作させた際に計測された第１温度と第２温度との温度差に基づいて、傾斜磁場コイルの発熱量を実測値として算出する。判定部は、予測値と実測値との差分値に基づいて、傾斜磁場コイルに異常が発生しているか否かを判定する。【選択図】図１
