MAGNETIC RESONANCE IMAGING INSTRUMENT

摘要

PROBLEM TO BE SOLVED: To produce a three-dimensional image expanded by a shorter electromagnet having a limited length of an excellent magnetic field region in a magnetic resonance imaging instrument. SOLUTION: In a magnetic resonance imaging instrument, an excitation pulse is imparted to the limited region 5 of a uniform magnetic field of a magnetic resonance imaging magnet hole. Fourier transform is performed on a gathered data sample to form a volume image of the limited region, and a motor 6 continuously moves a bed 3 of a patient so that an interesting region passes through an excellent magnetic field region. The data sample gathered is corrected to compensate for a movement for forming a longer volume image than the limited region.
