Navigating the Selection of Magnetic Resonance Imaging Shielding Systems

摘要

All shielding technologies are not equal and consideration of a host of factors should be given when selecting shielding, including performance requirements (E-Field, H-Field, Plane Wave, etc.), the application, quality of products, long-term performance, materials used, and construction methods. This letter explores shielding systems utilized for magnetic resonance imaging (MRI). Construction methods, quality of product, performance implications with associated data, as well as the impact to project costs and future operating costs are discussed. When evaluating the RF shielding effectiveness for MRIs, the primary concern is the potential risk of deleterious impact to the performance of the MRI rather than human exposure. The scope of this letter addresses the evaluation of the RF shielding’s impact on the performance of the MRI magnet.
