There is currently a great interest in combining magnetic resonance imaging (MRI) systems with Positron Emission Tomografy (PET). one the most potential advantages of this combination is the ability to obtain high resolution MR images of anatomoy while simultaeously collecting the functional imaging attainable with PET. One of the magor challange to this combination is the electro magnetic interference between PET detector and main magnet of MR system . by understanding the field inhomogeneity created by Pet we can design electromagnet correction coils to minimize magnetic interference
