Abstract
The ghost artifacts appearing in images produced by an MRI system are measured. An image of a reference phantom is acquired and the ghost artifacts are measured by cross correlating a ghost correlation matrix with the image. The ghost correlation matrix is produced from the image and the cross correlation is computed as the ghost correlation matrix is moved across the image along either the phase encoding or frequency encoding axes.
