Magphan® Phantoms are designed to perform a wide range of precision performance evaluations of Magnetic Resonance Imaging (MRI) Scanners.
The design criteria for the Magphan® phantoms are based on physicist, Dr. David Goodenough's extensive experience with MRI system evaluation and his well documented research into the quantification of image system performance tests. The test objects that make up the current Magphan® models embody two decades of scientific evaluation and field experience.
