PURPOSE:To make it possible to perform simultaneous display by superimposing the spin density distribution picture of a hydrogen nucleus and the spin easing time distribution picture, displaying the result, and adding the data of chemical change of texture due to disease to the shape data of the texture of a living body based on the spin density distribution picture. CONSTITUTION:An exciting signal is imparted to an exciting coil 12, which is provided in a magnet 17, through an RF exciting part 4 and an RF power amplifier 5 by the command of a computer 1. Then the NMR of the hydrogen nucleus in a living body, which is inserted in a magnet 17, is generated. At this time, a slant magnetic field is imparted to an X coil 14, a Y coil 15, and a Z coil 16 in a slant magnetic field coil. The NMR signal generated in a receiving coil 13 is guided to a computer 1. A picture is assembled from the position data and the signal intensity. Then a hydrogen nucleus spin density distribution picture is superimposed on a spin easing time distribution picture. At this time, the picture of the texture of the living body is displayed by the hydrogen spin density distribution picture in order to avoid the complication of the picture. An easing time zone, which is observed when the texture of the living body is chemically changed by the disease, is designated. The picture obtained in this time zone is superimposed on said distribution picture. Thus the part of the texture of the disease is observed on the picture of the texture of the living body. |
