Split magnetic resonance imaging system

摘要

A magnetic resonance imaging (MRI) system includes a split magnet system having a pair of MRI magnet housings separated by gap. A pair of main MRI magnets are disposed within respective MRI magnet housings. A plurality of buttress assemblies are attached to the MRI magnet housings. Some or all of the buttress assemblies are provided with removable connections to the MRI magnet housings. This allows for partial disassembly of the MRI system for improved transport and maneuverability for relocating the MRI system. The MRI system can include a gantry in the gap for supporting a radiation therapy system. Also, the removably buttress assemblies can be used for housing conduits, such as electrical and fluid conduits, between the pair of MRI magnet housings.

主权项

1. A magnetic resonance imaging (MRI) system comprising:
first and second MRI magnet housings separated by an MRI magnet gap; a first main MRI magnet disposed within the first MRI magnet housing; a second main MRI magnet disposed within the second MRI magnet housing; a first plurality of buttress sub-assemblies attached to the first MRI magnet housing; a second plurality of buttress sub-assemblies attached to the second MRI magnet housing; a plurality of central buttress connectors, each configured to be removably connected to a respective one of the first plurality of buttress sub-assemblies and to a respective one of the second plurality of buttress sub-assemblies; and a cooling system including a fluid conduit for carrying coolant for cooling the first and second main MRI magnets, wherein at least one of the first plurality of buttress sub-assemblies and at least one of the second plurality of buttress sub-assemblies is removably attached to the respective MRI magnet housing, and wherein the fluid conduit extends from within the first MRI magnet housing to within the second MRI magnet housing by routing through an interior of the at least one of the first plurality of buttress sub-assemblies that is removably attached, through an interior of the at least of the second plurality of buttress sub-assemblies that is removably attached, and through an interior of the central buttress connector removably connected to the respective one of the first plurality of buttress sub-assemblies and to the respective one of the second plurality of buttress sub-assemblies.
