Magphan® Quantitative Imaging Phantom (ADNI)

Precise, Comprehensive Measurement of 3d Spatial Distortion

The ADNI (Alzheimer's Disease Neuroimaging Initiative) Magphan® phantom is used for detailed measurements of volume distortion in MR scanners.

The ADNI Magphan® was originally developed for General Electric's MR research facility. GE developed an algorithm to process phantom images to evaluate spatial characteristics of MR scanners. This method for MR spatial assessment was adopted for use in the ADNI project. The ADNI Magphan® contains 165 polycarbonate spheres filled with copper sulfate and water solutions. The spheres are mounted on a series of polycarbonate plates and posts to maintain their fixed postions within the phantom. Measurements of the phantom are compared with the known positions of the spheres to give an accurate measurement of the distortion of the scanner.

Image Owl, Inc.

Image Owl, Inc., provides comprehensive data analysis, organization, and storage for users of the ADNI Magphan®. Image Owl software precisely measures, maps, and documents the volume stability or distortion. This service is purchased separately from the phantom.
