PURPOSE:To compensate the phase difference in nucleus precessions by impressing a 180 deg. pulse after determining a slicing surface, then impressing an inclined magnetic field of the same polarity as that of the time of determining the slicing surface. CONSTITUTION:A nuclear magnetic resonance video apparatus consists of a static magnetic field coil 1, a static magnetic field source 2, an inclined magnetic field coil 3, an inclined magnetic field source 4, a transmitting part 5, a transmitting coil 6, a receiving coil 7, a tuner 8, an amplifier 9, a detector 10, an A/D converter 11, a sequence controller 12 and a computer 13. A 90 deg. pulse is impressed simultaneously together with an inclined magnetic field Gz from the part 5 to a body to be inspected, next, an inclined magnetic field GXY is impressed, and furthermore the 180 deg. pulse is impressed from the part 5. Then the field Gz of the same polarity as that of the time of determining the slicing surface is impressed.
