I'm a researcher in the Istituti Ortopedici Rizzoli, Bologna, Italy.
My research line is above bone cement used in total hip artroplasty.
I have to evaluate the radiopacity of some new cement formulations.
In some previous works we calculated the optical density from the
x-ray films obtained from special specimens made with the cement
using a digital densitometer. Nowadays our x-ray apparatus, thanks to
the technology's evolution, does not directly print a film but
creates a digital image that could obviously be printed on
radiographic film.
I would like to use directly the digital image but I don't know how
to evaluate the optical density starting from that kind of medium.
Is there anyone that already did something like this?
Can I find some software (better if free) in the net?
Thanks to everybody is going to answer me
