Thanks for the input Nathaniel.

I was able to colorize the gray scale data by converting it to 8 bit, then applying a LUT, then converting it to 24 bit RGB and finally using Image/Color/Merge channels. Then I can display it as a 3D volume.

The only remaining problem is that the transparency function in the 3D viewer really does not work as it should (i.e. as an alpha channel). That is, you cannot see the inner layers of the volume through the outer layers of the volume. Does ImageJ have a plug-in that supports true transparency rendering through a 32 bit RGB image where 8 bits is an alpha value, or some other mechanism?
