We describe a new method to obtain an accurate
mapping of the bone mineral density which can be applied to any
area of the human skeleton in a live subject using conventional
CT scan imaging. The method involves direct measurement of
grey colour intensity from the CT image. The colour intesity mantains
a direct relationship with the Hounsfield Units, therefore the
optic density of a given area is related to the bone density. In our
study this method has been applied to the human femoral head
to obtain a three-dimensional topography of the bone density.
