    Abstract: An animal handling system for use in an MRD device, including: a first elongated enclosure having a proximal end, a distal open end and a first geometry, and a second first elongated enclosure having a proximal end, a distal open end and a second geometry. The first geometry comprises a first cross-sectional area which is larger than a second cross-sectional area of the second geometry. The first elongated enclosure is inserted into a first input port of the MRD device and the second elongated enclosure is inserted in a second input port of the MRD device diametrically opposite to second input port, such that on insertion of the first elongated enclosure into the first input port and insertion of the second elongated enclosure into the second input, the second elongated enclosure slides into the first elongated enclosure through the open distal end of the first elongated enclosure.

    Abstract: A system of performing inline measurements of flow rate, density, and rheology of a flowing fluid. The system includes a rheology measurement subsystem, a density measurement subsystem, and a pressure sensor for measuring the pressure of the test fluid within the vertical tube at a location y2 downstream from y1 and displaced vertically from y1 by a distance Δh.

    Abstract: A comparatively light and compact permanent magnet arrangement for an MRI apparatus has a pair of opposed permanent magnet arrays with a shimming system to adjust the uniformity and strength of a magnetic field in a central chamber of the apparatus. The MRI apparatus is used to examine the extremities of a patient to determine cardiovascular characteristics from an analysis of the blood flow through selected arteries in the extremity. The information collected can be used to calculate such characteristics as total cardiac output, blood flow, arterial wall thickness and elasticity and the presence of plaque.
