Fully 3D Wavelets MRI Compression

This paper deals with the implementation of 3D wavelets techniques for compression of medical images, specifically in the MRI modality. We show that at the same compression rate a lower loss of information can be obtained by using fully 3D wavelets as compared to iterated 2D methods. An adaptive thresholding step is performed in each sub-band and a simple Run Length Encoding (RLE) method for compression is finally used. A reconstruction algorithm is then implemented and a comparison study of the reconstructed image is then proposed, showing the high performance of the proposed algorithm.
