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.

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.

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.
