PROBLEM TO BE SOLVED: To provide a magnetic resonance imaging apparatus for easily confirming if measurement time is appropriate for a biological signal waveform input in real-time from a biological signal sensor attached to a subject.SOLUTION: A measurement control unit performs imaging sequence for measuring a nuclear magnetic resonance signal generated by a subject in applying a static magnetic field, a gradient magnetic field, and a high frequency magnetic field to the subject. The measurement control unit inputs a biological signal from a biological signal sensor attached to the subject, repeats processing for displaying a biological signal waveform 203 corresponding to at least one cycle on a synchronization measurement monitor 20a, calculates measurement time 208 related to synchronization measurement based on an imaging parameter to be set, and displays a display of a part corresponding to the measurement time of the biological signal waveform on a synchronization measurement waveform 201 in a manner to be different from the other waveform parts.SELECTED DRAWING: Figure 4 【課題】被検体に装着された生体信号センサからリアルタイムで入力される生体信号波形に計測時間が適しているかを容易に確認できる磁気共鳴イメージング装置を提供する。【解決手段】被検体に静磁場と傾斜磁場と高周波磁場を印加して被検体から発生される核磁気共鳴信号を計測する撮像シーケンスを実行する計測制御部は、被検体に装着された生体信号センサから生体信号を入力して、少なくとも１周期に対応する生体信号波形２０３を同期計測モニタ２０ａに表示する処理を繰り返し、設定される撮像パラメータに基づいて同期計測に係る計測時間２０８を算出し、生体信号波形の計測時間に対応する部分の表示を他の波形部分と異ならせて同期計測波形２０１に表示する。【選択図】図４
