Magnet assembly for magnetic resonance imaging (MRI) scanning system

An equine Magnetic Imaging Resonance (MRI) system, the equine MRI system comprising:

• a magnet assembly, comprising:
• a frame member movably positioned relative to a floor by a magnet movement unit (MMU), the frame member including a first end and a second end,
• a first arm extending laterally from the first end of the frame member and including a first magnet-pole assembly, the first magnet-pole assembly comprising a first central axis, a first magnet, a first pole shoe, and a first pole ring,
• a second arm extending laterally from the second end and including a second magnet-pole assembly, the second magnet-pole assembly comprising a second central axis, a second magnet, a second pole shoe, and a second pole ring, and configured to orient towards the first magnet-pole assembly while maintaining a gap therebetween, for positioning a body portion of a subject,
• a first clamp member and a second clamp member mounted about a peripheral side surface of the first magnet-pole assembly and the second magnet-pole assembly, respectively, the first and the second clamp members oriented to attenuate a leakage flux emanating from the first magnet-pole assembly and the second magnet pole-assembly, respectively, and
• the magnet-pole assemblies having a non-uniform first magnet and a non-uniform second magnet, wherein the thickness of the non-uniform first magnet in the center of the first magnet-pole assembly is less than the thickness of the non-uniform first magnet at the periphery of the first magnet-pole assembly and wherein the thickness of the non-uniform second magnet in the center of the second magnet-pole assembly is less than the thickness of the non-uniform second magnet at the periphery of the second magnet-pole assembly.
