Thanks, Robert. I attached two screen shots. I found that aliasing would only appears on the side of the cube that has not been filled. For example, the cube size is 100 x 100 x 20. If the cube is fully filled colour on all voxels, there is no aliasing on each surface. Once there is a section of voxels has not been filled colour, you can see aliasing from this section. I tried to increase the sample density, the colour becomes darker but the aliasing problem has not gone.

Volume rendering won't tend to be too sensitive/responsive to full screen anti-aliasing, rather then the way to improve visual quality with volume rendering is to increase the number of samples taken along the ray path when sampling the 3d texture. Could you post an example of the aliasing you are seeing, this will probably point to the problem.
