What to measure when measuring noise in MRI (Antwerpen 2013)

Slides from Talk given in Antwerpen University in 2013.

Motivation:

• Many papers and methods to estimate noise out of MRI data.
• Noise estimation vs. SNR estimation
• In single coil systems, variance of noise is a “good” measure.
• Complex systems: what are we really measuring? Is the variance of noise still valid?
