Abstract: An MRI phantom for calibrated anisotropic imaging includes a plurality of separate sheathed taxons or integral taxons sharing common taxon walls, wherein each taxon has an inner diameter of less than 5 microns. The taxons form taxon filaments that are combined to form taxon ribbons. The taxons may have an average inner diameter of less than 1 micron, specifically about 0.8 microns with a packing density of about 1,000,000 per square millimeter. The filaments may include structural features such as an outer frame and crossing support ribs and may further include a visible alignment feature that allows for verifying orientation of an individual filament. The taxons may be formed as taxon fibers manufactured using a bi or tri-component textile/polymer manufacturing process. An anisotropic homogeneity phantom may include frame members that support fiber tracks extending in orthogonal directions, wherein each fiber track is formed of taxons.

Abstract: An MRI phantom having an MRI compatible temperature measurement device having an MRI compatible body containing an MRI compatible fluid, wherein the device senses accurate temperature measurement within an MR Scanner environment using image processing of the contrast in signal between the areas of the image around the device and the fluid contained within the body of the device. The MRI Phantom may further include an internal expansion bladder device accomodating internal changes in pressure within the phantom, wherein the internal expansion bladder device includes frames supporting a pair of spaced membranes defining a chamber filled with a compressible gas.

Abstract: A universal, modular, temperature controlled MRI phantom for calibration and validation for anisotropic and isotropic imaging comprises an outer insulating shell configured to be received within an MRI chamber; an inner shell received within the outer insulating shell; a fluid conduits adjacent the inner shell for receiving temperature controlling fluid or gas cycling there-through; and a series of stacked layers of frames containing test points for the MRI phantom, each layer including at least one fiducial and including at least some anisotropic imaging test points in at least one frame and at least one isotropic imaging test point in at least one frame. The anisotropic imaging comprises hollow tubular textile fibers, wherein each hollow tubular fiber has an outer diameter of less than 50 microns and an inner diameter of less than 20 microns, wherein at least some hollow tubular fibers are filled with a fluid.
