This paper discusses a method of compressing three-dimensional biomedical images with losses, based on representing the data in the form of an octree. A modification of the method by geometrical normalization (equalization) of the image is proposed. It is shown that the proposed method has greater efficiency than the compression obtained when one exclusively uses the method based on an octree with losses but with a definite level of noise suppression.
