Abstract: The present disclosure provides a vertically retractable magnet field assembly for a Magnetic Imaging Resonance (MRI) system. The assembly can move from an upward raised position to a downward retracted position, and vice versa. The assembly includes a magnet configured with a bore for imaging a body portion of a subject. The bore defines an inner surface of the magnet and extends along a longitudinal axis of the magnet. The magnet includes at least one flux generating element disposed within the magnet and oriented such that each of the at least one flux generating element surrounds the bore. Each of the at least one flux generating element is configured to generate a magnetic field for magnetizing the body portion positioned within the bore to generate a visual representation of an anatomy of the body portion.

Abstract: Disclosed herein are embodiments for a standing equine magnetic resonance imaging device. The device includes two opposing planar power transmit coils facing each other. Each of the planar power transmit coils includes a plurality of radio frequency conducting planar rungs arranged to form concentric circles and a plurality of radio frequency conducting planar spokes extending from an outermost rung and connecting to each of the rung circles. At least one pin diode is positioned across the outermost rung circle. A plurality of tuning capacitors are positioned across the spokes.

Abstract: The present disclosure provides a magnet assembly for a Magnetic Resonance Imaging (MRI) system. The assembly includes a yoke having a frame member movably positioned by a magnet movement unit. A first arm extends laterally from a first end of the frame member and includes a first magnet-pole assembly having a first central axis. A second arm extends laterally from a second end of the frame member and includes a second magnet-pole assembly. The second magnet-pole assembly includes a second central axis and configured to orient towards with the first magnet-pole assembly while maintaining a gap therebetween, for positioning a body portion for magnetization. A first and a second clamp member are each mounted about a peripheral side surface of the magnet-pole assemblies, respectively. The clamp members are configured to attenuate a leakage flux emanating from the magnet pole assemblies.
