Abstract: A magnetic shielding mechanism for preventing penetration of metallic objects through an aperture, towards the open bore of an magnetic resonance imaging device, where the magnetic field is maximized. The magnetic resonance imaging device produces a fringing magnetic field that decreases with increasing distance (L) from the aperture. The mechanism includes at least one magnet with a magnetic field. The mechanism is affixed at a distance from the aperture of magnetic resonance imaging device.

Abstract: A method and system are provided for providing values for control signals for a pulsed magnetic resonance spectrometer such as an NMR spectrometer or an MRI apparatus. The AC output(s) corresponding to a particular signal (e.g. a magnetization or gradient pulse or pulse sequence) originating from a source spectrometer is measured and stored by an independent control unit. The digital output of the independent control unit is then connected to the digital input of the control electronics of a target pulsed magnetic resonance spectrometer, the value of the digital output varied until the AC output(s) of the appropriate signal source of the target spectrometer matches that of the corresponding output(s) of the source spectrometer, corrected, if necessary, for differences in magnetic field strengths.

Abstract: A non-destructive resonance (NDR) method of measuring and controlling an O2 fraction, a CO fraction, or a CO2 fraction in a gas process stream. The method includes: determining the resonance frequency of an off-line standard gas composition; scanning a predetermined characteristic parameter around the predetermined resonance frequency; plotting a first 3D chart to obtain a 3D vector; flowing gas through the NDR system; on-line scanning a corresponding on-line measured parameter around the resonance frequency, and recording the same; plotting a second 3D chart to obtain a 3D vector which precisely identifies the value of the second measured parameter; comparing a 3D standard first vector to the 3D measured second vector; and correlating between a relative characteristic parameter change and the change in the gas fraction.

Abstract: Generally, a system for generating a magnetic field having a desired magnetic field strength and/or a desired magnetic field direction is provided. The system can include a plurality of magnetic segments and/or a plurality of ferromagnetic segments. Each magnetic segment can be positioned adjacent to at least one of the plurality of magnetic segments. Each ferromagnetic segment can be positioned adjacent to at least one of the plurality of magnetic segments. In various embodiments, a size, shape, positioning and/or number of magnetic segments and/or ferromagnetic segments in the system, as well as a magnetization direction of the magnetic segments can be predetermined based on, for example, predetermined parameters of the system (e.g., a desired magnetic field strength, direction and/or uniformity of the magnetic field, a desired elimination of a magnetic fringe field and/or total weight of the system) and/or based on a desired application of the system (e.g., performing a magnetic resonance imaging of at least a portion of a patient and/or performing a magnetic resonance spectroscopy of a sample).

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.
