Boundary Detection and Reconstruction in Magnetic Resonance Imaging
Abstract
Gibbs ringing is a well known artifact that effects reconstruction of
images having discontinuities. This is a problem in the reconstruction of
magnetic resonance imaging (MRI) data due to the many different tissues
normally present in each scan. The Gibbs ringing artifact manifests
itself at the boundaries of the tissues, making it difficult to determine
the structure of the brain tissue. The Gegenbauer reconstruction method
has been shown to effectively eliminate the effects of Gibbs ringing in
other applications. This talk will present the application of the
Gegenbauer reconstruction method to neuro-imaging.
