Abstract: The present invention discloses methods, gantry, and room's infrastructure for maneuvering a portable open-bore magnetic resonance device with no fringing of its magnetic field (MRD) from at least one first location towards at least one static patient placed at at least one second remote location. The gantry comprises a transporting mechanism; and, an open-bore MRD, interconnected to the gantry by at least one maneuverable member. The MRD, by means of the gantry, is transportable from the first location to the second remote location adjacent the static patient. The aperture of the MRD's open-bore, by means of said maneuverable member, is directable towards a defined spatially orientation facing the static patient.

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 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: A neonate incubator for positioning a neonate within a magnetic resonance imaging (MRI) device is provided. The neonate incubator can include RF shielding that can provide RF shielding during imaging, for example, while life support tubes are connected to the neonate during MRI imaging. The RF shielding can include a door to mate with a bore of the MRI device to provide the RF shielding, and a RF channel that extends along an axis that is substantially parallel to a longitudinal axis of the neonate incubator from an interior chamber of the neonate incubator through the RF shielding door.

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 method of determining a NMR prediction result of a sample is provided. The method can include receiving a NMR spectrum of the sample and/or identifying a section of a ppm range in the NMR spectrum having a non-stationary peak. The method can include determining a modified data point for the NMR spectrum based on data points in the identified section. The modified data point can be determined such that the modified data point is a weighted average value of the data points in the identified section in the NMR spectrum. The method can include replacing the identified section in the NMR spectrum with the modified data point for the NMR spectrum to determine a modified NMR spectrum. The method can include determining the NMR prediction result of the sample based on the modified NMR spectrum and a calibration vector (e.g., using a partial least square (PLS) analysis).
