초록

Two methods can be used to correct the undesirable magnetic field of MRI. One is active shimming method and the other is ferro-magnetic shimming. Ferro-magnetic shimming method is more inexpensive, more convenient in operation and more effective on correcting magnetic field. So, nowadays, it is the general method for shimming the commercialized MRI magnet. We have developed a 1.5T MRI magnet and its ferromagnetic shimming system. Using the ferro-magnetic shimming system, we have improved the field homogeneity of the 1.5T MRI magnet.
