Hi everyone ,
im very new in imageJ and im not even sure what im gonna ask makes any sense or not but here is the question :
my project is about determining the bone mineral density of the lumbar spine , to do that I took x-ray images and now I need to analyse them with imageJ to extract to BMD at the end.
to do so I need to have the intensity of the beam , which I passed through my phantom and I need the intensity in keV at the end . Is it possible to get the intensity using imageJ ?
