The goal of this project is to develop an MRI phantom for the quantification of fat. This phantom will be used to test MRI techniques developed by the client for the imaging of fat in vivo. The phantom must contain samples of known physiologically relevant quantities of fat. The eventual purpose is quality control of MRI scanners that use fat-water contrast imaging.

The mechanical structure of the prototype has been built. A repeatable process has been developed which outlines the creation of the chemical components (emulsions) of the phantom. Several trial emulsions have been tested with MRI.
