Assessment Of Mineral Changes In The Spine With Computer Tomography Using A Calibration Phantom

A single energy technique for measuring and analyzing bone mineral content has been implemented on a Siemens (Somatom-2) head scanner. The measurement is based upon a reference phantom that contains various concentrations of potassium phosphate that is exposed simultaneously with the patient. The method facilitates the analysis of the current status of the patient compared to controls as well as the results of follow-up examinations.
