PURPOSE:To reproduce images which have small deterioration by providing a means which measures the time dependency of a slanting magnetic field and a means which reproduces an image on the basis of it. CONSTITUTION:A transmission system 13 sends amplitude-modulated high-frequency pulses to a high-frequency coil 13 according to an instruction from a sequencer 12. Consequently, a high-frequency magnetic field is applied to an object body 20. A magnetic field gradient generation system 16 applies slanting magnetic field gradient generation system 16 applies slanting magnetic fields GX-GZ in three directions to the body 20 according to an instruction from the sequencer 12. The response of the application of those magnetic fields is received by a reception system 14 through a coil 134. The reception system 14 sends two sequences of data sampled at the timing of an instruction of the sequencer 12 to a signal processing system 17. The processing system 17 makes the signal level distribution of an optional section or a distribution obtained by processing plural signals into an image, which is displayed on, for example, a CRT display. This system obtains images having less deterioration by using a measuring of the time dependency of the slanting magnetic fields. |
