he article deals with the problem of correcting the uneven intensity in magnetic resonance images. This problem is related to the features of the visualization equipment, may be caused by the instability of the field registration by magnetic coils and other technical reasons. The displacement field makes it difficult to use digital methods for recognizing objects in images and making a correct diagnosis. In this paper, it is proposed to use high- frequency filtering (rho filter, or ramp filter) to remove the distorting low-frequency systematic component. The results are illustrated by a model example and real processing of biomedical MRI images.
