Measurement of signal intensities in the presence of noise in MR images.

R M Henkelman.   

Abstract

Power spectrum or magnitude images are frequently presented in magnetic resonance imaging. In such images, measurement of signal intensity at low signal levels is compounded with the noise. This report describes how to extract true intensity measurements in the presence of noise.
