US Classification:

324307

Abstract:

An MRI apparatus and method comprises an MRI system having a plurality of gradient coils positioned about a bore of a magnet, and an RF transceiver system and an RF switch controlled by a pulse module to transmit RF signals to an RF coil assembly to acquire MR images. The magnet comprises a main coil former and a shield coil former arranged radially around the bore of the magnet, wherein a radius of the shield coil former is greater than a radius of the main coil former. The magnet also includes at least one main coil affixed to the main coil former, at least one shield coil affixed to the shield coil former, and at least one structural member affixed to the main coil former and to the shield coil former to provide structural support and enable longitudinal alignment adjustment between the main coil former and the shield coil former.

International Classification:

A47H 1/10

US Classification:

248317, 62 511, 292162

Abstract:

A suspension system for a cryostat includes a coupling mechanism, a fixation body, and a pin. The coupling mechanism is joined to an outer vessel and coupled with a strap. The fixation body is joined to an inner vessel. The fixation body extends between a front side that faces the coupling mechanism and an opposite receiving side with an interior channel extending from the receiving side to the front side. The channel defines a front opening in the front side and a rear opening in the receiving side. The pin is loaded into the fixation body through the rear opening in the receiving side of the fixation body with the strap looped around the pin and extending through the front opening to the coupling mechanism. The pin secures the coupling mechanism to the fixation body via the strap by engaging the fixation body inside the channel.
