Estimation of the noise in magnitude MR images.

J Sijbers1, A J den Dekker, J Van Audekerke, M Verhoye, D Van Dyck.   

Abstract

Magnitude magnetic resonance data are Rician distributed. In this note a new method is proposed to estimate the image noise variance for this type of data distribution. The method is based on a double image acquisition, thereby exploiting the knowledge of the Rice distribution moments.
