    摘要: The present invention provides an elongated active thermo-regulated neonatal transportable incubator (ANTI), having a main longitudinal axis with a proximal end and an opposite distal end comprising adjacent to at least one of the ends a temperature regulating vent (TRV). The TRV is configured to stream air from one end towards the opposite end substantially along the axis, and the ANTI is configured, by means of size and shape, to accommodate the neonate in parallel to the axis. Further the ANTI can be configured by means of size shape and material to at least partially inserted into an MRD having an open bore in its longitudinal axis, further accommodating the neonate parallel to the MRD bore. An incubator with a temperature regulating vent located outside the incubator and its base.

    摘要: Generally, a system for soothing a baby during imaging by an imaging device is provided. The system can include: a capsule incubator for positioning the baby within the imaging device, the capsule incubator can include: a bottom portion having an inner surface, a bed positioned on top of the inner surface for positioning the baby thereon, and one or more members coupled to the bottom portion that are positioned in a first position to open the capsule incubator and a second position to close the capsule incubator; a vibrational device including a vibrational element that extends from outside of the capsule incubator into the capsule incubator and is coupled to the bed to cause the bed to vibrate with a predetermined vibrational frequency, thus causing the baby to vibrate with the predetermined vibrational frequency.

    摘要: A premature neonate closed life support system (NCLSS) including: at least one chamber confining a cradle-like neonate support (CLNS) having suitable dimensions and geometric-configuration for accommodating at least one premature neonate having at least two operational configurations, said operational configurations comprising: a first operational OPEN configuration whereby said CLNS is adapted to couple said neonate to at least one life supporting system by means of at least one life supporting coupling line, prior to positioning said CLNS in a medical device; and a second operational air-tight CLOSED configuration whereby said neonate remains continuously coupled to said at least one supporting system by means of at least one life supporting coupling line, when positioning said CLNS within said medical device. The OPEN and CLOSED configurations are reversible.

    摘要: A portable nuclear magnetic resonance (NMR) device and a method of determining an oil concentration in water are disclosed. The portable NMR device can include a magnetic field assembly to carry out NMR measurements of water. The portable NMR device can include a housing to at least partly surround the magnetic field assembly and to substantially eliminate a magnetic fringe field generated by the magnetic field assembly outside the housing. The portable NMR device can also include an analysis module to receive the NMR measurement of the water and to determine, based on the received NMR measurements of the water, the oil concentration in the water.

    摘要: A method of reducing artifacts produced during Fast Spin Echo measurements made using permanent magnet NMR instruments. The method includes applying encoding gradients that do not switch signs throughout the experiment. Prior to the 90° RF pulse, a strong RM gradient pulse is given to produce a dominant and constant residual magnetization. The encoding is done through the combination of encoding gradients with the aid of the 180° RF pulses of the echo train. A first constant encoding gradient is given before the first 180 pulse. Then two variable encoding gradients are provided after each 180 pulse; one applied prior to and one applied subsequent to each acquisition in the echo train.

    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).
