Patent ID: 8224048

Claim:
In a computer including a memory, and a processor for executing computer implemented code stored in said memory, a computer implemented method of correcting a magnetic resonance (MR) image comprising a plurality of image points, each having a coordinate x and a measured intensity l m (x) dependent on x, said method comprising: selecting seed points having a same expected true intensity from said image points, each seed point having a coordinate x s ; determining an intensity correction function l f (x) by fitting measured intensities of said seed points l m (x s ), to l m (x s )=l f (x s ), wherein l f (x) is a non-zero order polynomial function having coefficients, wherein values-of said coefficients are determined by said fitting; and obtaining a corrected image comprising corrected image points, each corrected image point having a coordinate x c and a corrected intensity l c (x c ), l c (x c ) being calculated according to l c (x c )=l m (x c )/l f (x c ), wherein l f (x c ) is the determined polynomial function l f (x) applied to coordinate x c and l m (x c ) is an initial value of a measured intensity at said coordinate x c .
