Abstract

See full text

A method for denoising magnetic resonance images includes estimating a normalization field corresponding to a magnetic resonance imaging device and acquiring a non-normalized image from the magnetic resonance imaging device. A noise level estimation process is performed with the non-normalized image to yield a noise level. The normalization field is applied to the noise level to yield a potentially inhomogeneous noise-level map and to the non-normalized image to yield a normalized image. An adaptive polynomial filtering process is performed using the normalized image and the potentially inhomogeneous noise-level map to yield a denoised image.
