Abstract: A portable nuclear magnetic resonance (NMR) device and a method of determining an oil concertation 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.

Abstract: Method of determining a velocity profile of a fluid flowing through a conduit, the method including applying a saturation pulse on spins of magnetic field-sensitive nuclei in the fluid, measuring a signal of the fluid to determine position of the magnetic field-sensitive nuclei, the measurement carried out at a recovery time ‘TR’ and at a distance ‘d’ within the conduit, determining within the conduit a radial distance ‘r’ characterized by a local minimum in the measured signal, wherein the radial distance ‘r’ is measured from the center of the conduit, and determining a velocity profile of the fluid at the radial distance, based on the magnetic field-sensitive nuclei.

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 of reducing the effect of object movements along MRI imaging. The method includes: acquiring a sequence of MRI consecutive images of an object; storing on a computer readable medium, for each of the images, at least one parameter p indicating spatial image orientation at which the image was taken; analyzing the sequence of the images for detection of the object movement; and tagging images of at least one movement of the object.
