MAGNETIC RESONANCE IMAGING APPARATUS AND GRADIENT MAGNETIC FIELD FORMING DEVICE |
| 摘要 |
PROBLEM TO BE SOLVED: To improve quality of images by preventing distortion in cross-sectional images by suppressing an influence of an eddy current. SOLUTION: A gradient pulse correction part 28 corrects a gradient pulse to reduce the influence of an eddy current magnetic field in a gradient magnetic field based on an amplitude A<SB>ki</SB>of the eddy current an eddy current storing part 29 stores corresponding to an amplitude G<SB>k</SB>of a gradient pulse g(t) and a time constantτ<SB>ki</SB>.
