Since 1972 a system for analytic roentgen stereophotogrammetry utilizing tantalum indicators has been in use in Lund, Sweden, and by 1977 more than 3000 stereo roentgenograms have been evaluated with that system. Patient investigations started March 1973, and by March 1978, 200 patients have been marked with tantalum indicators and investigated for longer or shorter periods with the method. The reasons for the investigations have been very variable but growth disturbances, craniofacial anomalies, disorders of the spine and visceral tumours have dominated. The aim has been to evaluate the effects of medical and surgical treatments. The high technical reliability and versatility of the method has led to accurate and easy to interpret results with a distinct clinical significance.
