PURPOSE:To shorten a scanning time by placing magnetism entirely inside and outside a slice surface in a thermally balanced state forcibly and accurately when a sequence for one view is finished. CONSTITUTION:A control circuit 2 flows a current to a static magnetic field coil 1 to apply a static magnetic field to an object body, and in this state a controller 20 flows a current to a Z slanting magnetic field coil 3 through a control circuit 4 to apply a Z slanting magnetic field. Then, an X slanting magnetic coil and a Y slanting magnetic field coil are excited. An NMR resonance signal obtained from a detection coil 8 is inputted to a computer 13 through a preamplifier 9, phase detector 10, and wave memory 11. Then, the computer 13 processes the NMR resonance signal as specified to form a tomographic image. |
