ABSTRACT:
A magnetic resonance diagnosis apparatus is capable of performing magnetic tagging of a three-dimensional region to visualize three-dimensional motion or to quantitatively handle the motion. In this apparatus, a control unit controls a gradient magnetic field power source of each axis so that magnetization by gradient magnetic fields generated from a gradient magnetic field coil describes a three-dimensional orbit inside space and performs magnetic tagging for a predetermined three-dimensional region of an object by adjusting a magnitude of gradient magnetic field pulses, pulse intervals and application times. Consequently, one can provide an MRI apparatus capable of more flexibly observing motion of organs and flow of blood.
