    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: A neonate positioning assembly for positioning a head of a neonate within a radio frequency coil of a magnetic resonance imaging is provided. The neonate positioning assembly allows for the head of the neonate to be positioned within a field of view of the radio frequency coil without repositioning the neonate on the positioning assembly.

    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.

    Abstract: 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.

    Abstract: A magnetic resonance imaging (MRI) system is provided. The MRI system can include a magnetic field device to generate a magnetic field within a measurement volume and to generate a magnetic fringe field external to the measurement volume. The MRI system can include a ferromagnetic housing to envelop the magnetic field device. The housing can have a first portion and a second portion, where thickness of the first portion is different from thickness of the second portion. The MRI system can include a plate having a plate opening and positioned external to the housing at a predetermined distance from the housing. In some embodiments, the magnetic fringe field generated by the MRI system can be asymmetric with respect to a center of the measurement volume.
