Hello, I don't usually read this group so I hope that this is the right group to post to. My lab is just getting into working with CT data. We are currently using Sunvision on a Sparcstation 1+. Our CT machine (Deltascan 2010) produces 256 x 256, 16 bit images. Some of the problems that we have had are in scaling the data to 8 bits for Sunvision. We have had some luck in displaying images, but there seems to be some degradation between what the CT machine displays and what we are able to display. Our ultimate goal is 3D volume rendering of stuctures from the CT slices. I am looking for info in the following areas: 1. quanitizing of data from 16 bit to 8 bit (I have seen some info on converting from 24 bit color to 8 bit, but nothing on 16 bit grayscale to 8 bit grayscale) 2. Should we be using the Delta (Hounsfield?) values for the reconstruction and where can I get some info on calulating these values from our data (our radiology department knows how to work the machine, but that is all) Thanks, Jim Snell, DVM, MS Department of Veterinary Anatomy and Public Health jim@sniff.tamu.edu jim@cssun.tamu.edu
