    Abstract: Radiofrequency (RF) coil unit and a housing for the RF coil unit is provided. The RF coil unit can include a substantially annular body having a concave indent along a longitudinal direction along the substantially annular body such that when a head of the patient is inserted into an interior of the substantially annular body, at least a portion of the head of the patient is viewable and accessible from a location exterior to the substantially annular body. The housing for the RF coil unit can include a channel to receive the RF coil unit of a MRI device. The housing can enclose regions with high voltages (e.g., 1000 Volts) and/or separate these regions from patient body parts by, for example, including insulating material, thereby enhancing a safety of the patient.

    Abstract: A protective sleeve reduces electromagnetic energy propagation from the magnet bore of a magnetic resonance imaging device (MRD) to the surrounding environment and prevents electromagnetic energy in the surrounding environment from contaminating an MRI reading. The protective sleeve comprises a distal portion configured for insertion within the bore and a proximal portion attachable to the MRD aperture. The sleeve is configured for inserting a body part for insertion within the MRD's open magnet, with the imaged portion of the body part protruding from the distal end of sleeve into the MRD's volume of interest. The sleeve comprises, or is connected to, one or more sensors configured to detect movement, acceleration or dislocation of at least one portion or segment of the body part to be scanned.

    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.

    Abstract: A maneuverable RF coil assembly, useful for being maneuvered at both positions: (i) over at least a portion of a neonate immobilized within a cradle at time of MR imaging; and (ii) below or aside the cradle when it is not required for imaging. The maneuverable RF coil assembly comprises at least one RF coil and maneuvering mechanism. The maneuvering mechanism comprises both: (i) a linear reciprocating mechanism for approaching or otherwise drawing away at least one coil to and from the neonate; and (ii) tilting mechanism for placing at least one coil away from the neonate.

    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.
