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.

A jacket for radio frequency (RF) shielding a Magnetic Resonance Device (MRD) from external environment electromagnetic interference during its operation, which allows for homogenized imaging conditions. The RF shielding jacket is sized and shaped like an envelope to accommodate the MRD, with at least a portion of the RF shielding jacket including an electromagnetic interference shield. The RF shielding jacket is also combined with passive temperature insulating properties.

Devices and methods for providing an adjustable open-bore magnetic resonance device (MRD) that enable personalized accommodation for users of different sizes. The MRD includes a first main magnetic source and a second main magnetic source in a face-to-face orientation. The magnetic sources are separated by a distance that is adjustable by way of an endoskeletal height adjuster. In some embodiments, a superconducting electromagnet coiled around an oval defines the magnetic volume of interest. In such embodiments, the perimeter of the oval includes a plurality of trapezoid elements housing the coil of the electromagnet, and the trapezoid elements can be moved outwards and inwards relative to the ovals center in the plane of the oval.
