[The development of an active shimming system for 0.2T open-style permanent magnet MRI].
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.
