Dear Biomch-L subscribers,
Our lab is interested in creating a calcium hydroxyapatite
calibration phantom with a range of densities so that we may relate
CT attenuation data to equivalent hydroxyapatite density. As an
initial step, we suspended hydroxyapatite powder in a gelatin
solution. Unfortunately, the hydroxyapatite settled out before the
gelatin set in. We would greatly appreciate any information
pertaining to 1) substances for hydroxyapatite powder suspension, 2)
ensuring uniform density, and 3) any other helpful tips or tricks you
have picked up through experience. References on the topic would be
helpful as well. Of course, I will compile and post all responses.
Thanks for your help,
Brent
