The feasibility of triple-energy absorptiometry for the determination of bone mineral, Ca and P in vivo.
The theoretical feasibility of triple-energy absorptiometry in general and the experimental conditions when using triple-energy absorptiometry for the determination of bone mineral, elemental calcium and phosphorus content in vivo have been investigated. A theoretical analysis of the decomposition of the mass attenuation coefficients is presented and discussed. The main obstacle to the effective use of triple-energy absorptiometry in vivo is the large number of pulses which must be detected to reduce the statistical fluctuations.
