IPC: G01R33/48
Filed: 1984-10-30
Abstract: PURPOSE:To improve response and to shorten a scanning time, by forcibly directing magnetism to a z'-axis direction by using a control means having sequence function. CONSTITUTION:A first magnetic field (a z-gradient magnetic field Gz<+>) is applied to an object to be inspected to bring all directions of magnetism M to a positive z-axis direction. When a first 90 deg.x pulse and magnetic fields Gx, Gy are applied, the magnetism M of each part is directed as shown by the drawing. A first nuclear magnetic resonance signal is detected and comes to a one projection signal. When a first 180 deg.-x pulse is applied to the whole of the object to be inspected and, thereafter, gradient magnetic fields Gx, Gy are applied, magnetization M is rotated as shown by the drawing and a gradually increasing second nuclear magnetic resonance signal is detected. After this point of time, Gz<-> and Gz<+> are imparted and a second 90 deg.-x pulse is imparted to the object to be inspected to align all directions of magnetization M of the whole of the object to be inspected to a -z-axis direction. The directions of the magnetization M are aligned in the +z-axis direction all together. At the point of time when magnetization M is perfectly directed upwardly, one-time sequence is finished and similar sequence is repeated on and after.
