Nowadays manyMRI scans can give 3D volume data with different contrasts, but the observers may want to view various contrasts\nin the same 3D volume.The conventional 2D medical fusion methods can only fuse the 3D volume data layer by layer, which may\nlead to the loss of interframe correlative information. In this paper, a novel 3D medical volume fusion method based on 3D band\nlimited shearlet transform (3D BLST) is proposed. And this method is evaluated upon MRI T2? and quantitative susceptibility\nmapping data of 4 human brains. Both the perspective impression and the quality indices indicate that the proposed method has a\nbetter performance than conventional 2D wavelet, DT CWT, and 3D wavelet, DT CWT based fusion methods.
