Abstract:
1. A magnet vent assembly for venting a cryogenic gas from a superconducting magnet of an MRI system comprising a magnet exhaust and an exhaust vent, the assembly comprising: a first burst disc comprisinig a first inlet and a first outlet; a second burst disc comprising a second inlet coupled to the first inlet, and a second outlet coupled to the first outlet; a first valve in operable communication with the magnet exhaust, the first burst disc, and the second burst disc; and a second valve in operable communication with the exhaust vent, the first burst disc, and the second burst disc; wherein the first valve is configured to switchably direct a flow path of cryogenic gas from the magnet exhaust through either of the following: the first burst disc and the second burst disc; and wherein the second valve is configured to switchably direct a flow path of cryogenic gas to the exhaust vent from either of the following: the first burst disc and the second burst disc; wherein the first valve and second valve are linked to prevent the blockage of a flow path of the cryogenic gas to the exhaust vent.
