摘要： A magnetic resonance imaging apparatus including a pulse sequence control unit, which controls a predetermined pulse sequence of applying a high frequency magnetic field and a gradient magnetic field to an object in a static magnetic field to collect echoes; and an image reconstructing unit that reconstructs an image based on the collected echoes. The pulse sequence control unit includes a spatial resolution control section which sets a spatial resolution A in the readout gradient magnetic field direction of the reconstructed image; and a gradient magnetic field intensity control section which applies a readout magnetic field that causes the spatial resolution B determined by the readout gradient magnetic field intensity and the sampling period to become coarser than the spatial resolution A. The image reconstructing unit reconstructs an image with the minimum unit of the spatial resolution A taken as one pixel width in the readout direction of the reconstructed image.
