Filed:

Apr 27, 2020

Appl. No.:

16/859444

Inventors:

- Sharpsburg PA, US
- Pittsburgh PA, US
John Dzikiy - Pittsburgh PA, US
Walter Schneider - Pittsburgh PA, US
Richard A. Shaffer - Apollo PA, US

International Classification:

G01R 33/58
A61B 5/055
G09B 23/28
G01R 33/31
G01R 33/563

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.
