X-ray densitometry

Since Chalker et al. (1985) I have been unable to find any more 
work related to x-ray densitometry of corals. I would appreciate if 
anybody could send me references to any articles dealing with this topic 
post 1985. Also, does anybody know why this method for measuring coral 
skeletal density has not been used in research? Or has it?

Try the following articles. David  Barnes of the AIMS in Townsville was 
working rather a lot with x-ray densitometry.
