Meet Phannie, NIST's Standard 'Phantom' for Calibrating MRI Machines (2 of 2)

Caption

Phannie is the first "phantom" for calibrating magnetic resonance imaging (MRI) machines that is traceable to standardized values. The plastic sphere is about the size of a person’s head and filled with 100 smaller spheres used as contrast-enhancing agents and measurement reference markers. NIST researchers in Boulder, Colo., built Phannie, and tested it on an MRI scanner at the University of Colorado Brain Imaging Center.
