Abstract
For the purpose of accurately measuring and correcting a phase error in spins in a phase axis direction, a gradient magnetic field having an integral value of zero is applied in the phase axis direction during a time period between first and second 180° excitations to read out a first spin echo SE a gradient magnetic field having an integral value of zero is applied in the phase axis direction during a time period between second and third 180° excitations to read out a second spin echo SE and a phase error due to an effect of residual magnetization Gp is determined based on these spin echoes.
