摘要：

PROBLEM TO BE SOLVED: To improve time resolution of time-series images in a high-speed photography having a training measurement and a regular measurement.

SOLUTION: A magnetic resonance imaging method is provided, which comprises an information acquiring step for monitoring information of a photographing object, a fluctuation determination step for determining a fluctuation of the photographing object using the information monitored by the information acquiring step, a training step for carrying out a measurement that acquires only a low-frequency region of a measurement space, a regular measurement step for carrying out a measurement that thins out the number of phase encodings within the measurement space, and an image reconstructing step for reconstructing an image using signals acquired by the training step and the regular measurement step. In the magnetic resonance imaging method, the information acquiring step, the fluctuation determination step, the training step, the regular measurement step and the image reconstructing step are repeated to acquire continuous time-series images. During the training step, the number of phase encodings of the low-frequency region to be acquired is changed referring to the determination result of the fluctuation determination step.
