    Abstract: A mechanical clutch for preventing damage to a capacitor of an MRI device. The clutch prevents the application of excessive torque via the tuning rods of the gradient coil of the MRI device. The mechanical clutch allows the tuning rods to slip (disengage) when the capacitor reaches the end of its adjustment range.

    Abstract: An MRI device for providing high-contrast, high-resolution images of a fluid. The device includes: an envelope for at least partially confining the fluid; a plurality of magnets located at least partially around the envelope; and a CPU to process the images, including a computer readable medium containing instructions for generating at least one third image superimposing at least one image of the first images with at least one image of the second images, whereby a high-contrast, high-resolution real-time continuous images of the fluid is obtained.

    Abstract: An animal handling system for use in a magnetic resonance device (MRD) device, including: a first elongated enclosure having a proximal end, a distal open end and a first geometry, and a second elongated enclosure having a proximal end, a distal open end and a second geometry. The first geometry comprises a first cross-sectional area that is larger than a second cross-sectional area of the second geometry. The first elongated enclosure is inserted into a first input port of the MRD device and the second elongated enclosure is inserted in a second input port of the MRD device diametrically opposite to first input port. The first elongated enclosure and the second elongated enclosure are inserted into the respective input ports, the second elongated enclosure slides into the first elongated enclosure through the open distal end of the first elongated enclosure.

    Abstract: A magnetic resonance imaging (MRI) system is provided. The MRI system can include a magnetic field device to generate a magnetic field within a measurement volume and to generate a magnetic fringe field external to the measurement volume. The MRI system can include a ferromagnetic housing to envelop the magnetic field device. The housing can have a first portion and a second portion, where thickness of the first portion is different from thickness of the second portion. The MRI system can include a plate having a plate opening and positioned external to the housing at a predetermined distance from the housing. In some embodiments, the magnetic fringe field generated by the MRI system can be asymmetric with respect to a center of the measurement volume.
