- 摘要：
PROBLEM TO BE SOLVED: To provide a nuclear magnetic resonance imaging device applicable of a parallel nuclear magnetic resonance imaging method even to a moving image, so as to quickly produce a degradation-free image effective for diagnosis.
SOLUTION: This MRI device using a plurality of receiving coils, which have detection sensitivity regions spatially and partially overlapped and also divided from each other, measures echo signals continuously, following occurrence of transverse magnetization by high frequency pulses. Using a part of the continuously-measured echo signals, it calculates sensitivity-distribution in each coil, and then reconstitutes the image based on the calculated sensitivity-distribution and the continuously-measured echo signals.
