| Abstract: | This paper introduces the basic structure,operation principle as well as shimming method of an active shimming system ,which was developed for 0.2T open style permanent magnet MRI. In the end, a group of spin echo images(T1 weighted and T2 weighted) produced by the 0.2T MRI are given to demonstrate the satisfactory shimming performance of this active shimming system. |
