Abstract:
1. A magnetic resonance imaging apparatus comprising, a high frequency magnetic field generation means for generating a high frequency magnetic field to be applied on an examination target that is placed in an imaging space where a static magnetic field is generated, a gradient magnetic field generation means for generating a gradient magnetic field to be applied on the examination target, a transfer means being movable for mounting the examination target thereon, a receiving means for receiving a magnetic resonance signal generated from the examination target, an image reconstruction means for reconstructing an image of the examination target based on the magnetic resonance signal being received, a control means for controlling operation of each means, and a display means for displaying the image being reconstructed, wherein, the control means receives the magnetic resonance signal more than once, while the transfer means is moving, and controls the gradient magnetic field generation means and the receiving means in such a manner that an application amount of the gradient magnetic field in a moving direction of the transfer means is changed every receipt of the signal, and the image reconstruction means determines a magnetization map of the examination target in a field of view wider than the imaging space, in such a manner that a sum of the square of an absolute value of a difference is minimized, the difference between the signal being received and a signal calculated from the magnetization map set as a variable.
