Abstract

The detailed analysis of residual magnetization in permanent magnet type MRI is important for the improvement of MRI image. The behavior of residual magnetization produced by the z-gradient coil is already reported. As 3-D analysis is strictly required for investigating the residual magnetization produced by the x- or y-gradient coil, the report about such a behavior is few. In this paper, the minor loop and residual magnetization produced by the x-gradient coil in a 3-D model are examined. The useful knowledge for understanding the behavior of disturbance field due to the residual magnetization in the pole piece etc. is obtained.
