A new image processing method reduces Nonuniform Rotational Distortion (NURD)
in
a medical image acquired using a rotating transducer. The image comprises a plurality
of image vectors having texture. In a preferred embodiment, the image processing
technique computes an average frequency of the texture for each image vector and
estimates an angle for each image vector based on the average frequency for the
respective image vector. The image processing technique then corrects for NURD
by remapping each image vector to the estimated angle for the respective image vector.
