Abstract:
A radiofrequency (RF) shielding channel for a magnetic resonance imaging (MRI) device is provided. The RF shielding channel can include at least one conductive layer having a proximal end and a distal end. The RF shielding channel can include a connector to removably attach the proximal end of the at least one conductive layer to a bore of the MRI device. The at least one conductive layer can be extended in a longitudinal direction with respect to the bore of the MRI device between a first predetermined longitudinal dimension and a second predetermined longitudinal dimension, such that a RF shield is formed from the bore of the MRI device to the distal end of the at least one conductive layer. The RF shield can prevent an external RF radiation from entering the bore of the MRI device and/or an RF radiation emitted by the MRI device from exiting the bore.

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:
The present invention discloses a method and systems for detecting a target biochemical molecular species whose main component is water. In one aspect, the method comprises steps of: (a) obtaining a sample whose main component is water; (b) providing Functionalized Paramagnetic Particles (FPP) comprising a paramagnetic core and a moiety configured to interact with the target biochemical molecular species; (c) contacting the FPP with the sample; (d) exposing the sample to an applied magnetic field; (e) measuring a change in a nuclear relaxation property of the sample, caused by the interaction between the FPP and the biochemical molecular species in the applied magnetic field; and (f) correlating the change to the presence of the biochemical molecular species in the sample. According to a main aspect of the invention, a change in T.sub.1 nuclear relaxation property of the water protons in the sample is correlated to the presence of the target biochemical molecular species.
Abstract:
A magnetic resonance system (MRS), useful for imaging a patient, comprising: (a) a magnetic resonance device (MRD) for imaging a patient, comprising an open bore, the MRD at least partially contained in an envelope comprising in its circumference at least one recess; and, (b) an MRI-safe cart made of MRI-safe material, comprising a substantially horizontal base and at least one substantially horizontal incubator above the base, the base and the incubator are interconnected by at least one pillar. At least a portion of the cart and the MRD are configured to fit together such that at least a portion of the incubator is reversibly housed within the MRD, and further at least a portion of the base is reversibly housed within at least one recess.
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:
A shutting assembly for a magnetic resonance imaging device (MRD) bore aperture, comprising at least one first movable portion and at least one second portion affixed to the MRD, wherein the shutting assembly further comprising a normally closed or normally open sliding mechanism. The sliding mechanism couples at least one first moveable portion to at least one second portion affixed to the MRD, thereby enabling a reciprocal movement of at least one first moveable portion parallel to the MRD bore aperture in an upwards and downwards directions in respect to at least one second portion affixed to the MRD.
