Abstract
PURPOSE:To obtain a highly accurate calculation image, by using algorithm to which a signal intensity formula considering the angle of rotation of the actual spin of the first 180 deg.-pulse in a reversal restoration method or the selection characteristic of a slice direction is adapted. CONSTITUTION:A high frequency pulse transmitter 202 is controlled by a sequence control part 201 and an inclined magnetic field driving part 204 is controlled through a magnetic field control part 203. The MR signal generated from an object to be examined is taken in a receiver 205 and the reconstitution of an image or the calculation of a calculation image is performed by a processing apparatus 206 and the obtained image is displayed on a display 207. The processing apparatus 206 calculates a longitudinal relaxing time image on the basis of algorithm to which a signal intensity formula considering the angle of rotation of the actual spin of the first 180 deg.-pulse or the selection characteristic of a slice direction is adapted.
