PURPOSE:To enable the comprehension of physiological dynamism, by providing a plurality of detection coils and a plurality of receiving systems at positions separated spatially. CONSTITUTION:A plurality of detection coils 3 which are located at positions different from an irradiation coil 2 for applying a high frequency pulse for resonance excitation are arranged in a DC magnet 1 for producing a uniform DC magnetic field so as not to interfere with one another and a sample 4 to be measured is placed therein. The coils 3 include a function of being movable according to the measuring position of the sample 4. A frequency source 5 generates a high frequency determined by the DC magnetic field and a measuring nuclide and the frequency is amplified it with a power amplifier 6 to be applied to the coil 2. Then, a high frequency magnetic field with a resonance frequency is generated at a measuring part of the sample 4 to excite a resonance. the attenuation of the resonance signal of the frequency is picked up simultaneously with the coil 3, after amplified with a receiver 7, detected in the phase according to the frequency of the frequency source 5 and converted into a low frequency range of signal, which is converted into a digital value with and A/D converter 9 at a specified time interval. The values thus obtained are read out with a CPU10 to be memorized into a memory 11 sequentially.
