    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: A system for performing inline measurements of flow rate, density, and rheology of a flowing fluid is disclosed, comprising: (a) a rheology measurement subsystem comprising: a horizontal tube of internal radius rH; means for measuring a velocity profile of a test fluid flowing through said horizontal tube at a distance x0 from its upstream end; and means for determining wall shear stress at a boundary between said flowing fluid and an inner surface of said horizontal tube; (b) a density measurement subsystem comprising: a vertical tube of internal radius rV in fluid connection with said horizontal tube; a pressure sensor for measuring the pressure of said test fluid within said vertical tube at a location y1; and, (c) a pressure sensor for measuring the pressure of said test fluid within said vertical tube at a location y2 downstream from y1 and displaced vertically from y1 by a distance Δh.

    Abstract: An incubator's closure assembly adapted to shut the aperture of a magnetic resonance imaging device (MRD) having an open bore extended along the MRD's longitudinal axis with a distal end and proximal end, the bore is terminated by the aperture located in the proximal end, into which a neonate's incubator is inserted, thereby shutting the MRD bore aperture. The closure assembly comprising at least one U-shaped conduit having (i) an array of distal and proximal sealing walls, both are substantially perpendicular to the longitudinal axis and having upwards and downwards directions, and (ii) a recess in between the walls having length, in upwards to downwards direction, and width, in distal to proximal direction, each of the proximal wall and the distal wall comprising a cutout at opposite directions, and wherein in the recess, the ratio of length to width is greater than a predefined value n.
