Our most versatile quantitative MRI (qMRI) phantom for MRI’s used in a wide range of applications

The qMRI System Phantom consists of a plastic sphere the size of a person’s head encapsulating measurement reference markers and 100 spheres with 42 containing contrast-enhancing agents. The System Phantom can be modified for application specific needs and the components are always traceable to NIST, providing an exceptional tool for quantitative standardization of MRI scanners performing a variety of diagnostic procedures.
