The Rician distribution of noisy MRI data
H Gudbjartsson, S Patz - Magnetic resonance in medicine, 1995 - Wiley Online Library
The image intensity in magnetic resonance magnitude images in the presence of noise is
shown to be governed by a Rician distribution. Low signal intensities (SNR< 2) are therefore …
