PROBLEM TO BE SOLVED: To non-invasively provide an impedance distribution by changing the power amount for generating a high frequency magnetic field, obtaining plural magnetic resonance images of different flip angles, performing an image processing among the obtained magnetic resonance images and obtaining impedance distribution images inside a subject. SOLUTION: When a computer 10 supplies operation start signals, a timing controller 20 supplies control signals to a switching circuit 40, connects an RF coil 70 and an output power amplifier 42, supplies the control signals to the output power amplifier 42, supplies pulses equivalent to the flip angle α1 to the RF coil 70 and obtains the magnetic resonance images at the flip angle α1 of the testee body 50 from resonance signals detected in the RF coil 70. Then, the magnetic resonance images at the flip angle α2 of the testee body 50 are obtained. Then, the comparison processing of the intensity distribution of images is performed to the magnetic resonance images of the flip angle α1 and the magnetic resonance images of the flip angle σ2 is performed and an image processing result is displayed at a display 14. |
