Abstract: 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 oval's center in the plane of the oval.

Abstract: A method of operating a magnetic resonance imaging (MRI) device for habituating a patient and/or user to acoustic-noise of the device's operation. The method includes: listing a required set of the pulse-sequences (RSPS) for the patient, modifying the RSPS to a new set of sequences (NSPS) further comprising at least one demo-sequence, and operating, by means of generating the pulse-sequences, according to the NSPS. The demo-sequence is a redundant sequence, used solely for acoustic-sound habituation, while the originally listed RSPS are used for medical readings, thereby habituating the patient and/or user to the acoustic-noise of the operation.

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.
