Hi

You could possily use the plugin I recently submitted:  
http://rsb.info.nih.gov/ij/plugins/radon-transform.html
This produces back projection data from 8 and 16 bit images. The
projection data can be saved as a text file.
I have not used the volume J back projector, so am not familiar with it.
