摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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).

摘要： 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.

摘要： A pneumatic sample feedway that is embeddable into a magnetic resonance imaging (MRI) device. The feedway includes: a plurality of capsules enclosing a biological tissue sample; and a conductor pipe connected to a source of a compressed fluid. The pipe receives a train of the capsules and pneumatically forwards the train into the MRI device. The pipe has a proximal terminal that loads the train of capsules into the pipe.
