2001 Proceedings 2nd Annual IEEE International Symposium on Bioinformatics and Bioengineering (BIBE 2001)  
This makes it easier to transmit them over the network and allows for progressive image refinement. The transmitted 2-D cross-sections are then transformed and reconstructed into a 3-D volume.  ...  For this we need to extract sub-volumes of the data set. These sub-volumes are then transmitted and rendered at a higher resolution than the rest of the data set.  ...  After transforming the data set in x-direction (Figure 4), this 3-D array is then transformed along the y-direction (Figure 5). Finally, the 3-D array is transformed along the z-direction.  ...
