PHASE DEVIATION MEASURING METHOD OF FID SIGNAL AND SE/STE SIGNAL, MR IMAGING METHOD AND MRI DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an image without any band artifact. SOLUTION: The phase of an RF (radiofrequency) pulseαis adjusted to correct a zero-order phase deviation of FID (Free Induction Decay) signal and SE (spin-echo)/STE (stimulated-echo) signals by a pulse sequence collecting data in a SSFP (steady-state free-precession) state and a correction pulse correcting a primary phase deviation of the FID signal and the SE/STE signals is added to a lead axis pulse. This constitution can suppress the band artifact. COPYRIGHT: (C)2003,JPO
