Abstract:
A “cloverleaf” low energy germanium detector array has been assembled for the purpose of in vivo bone lead measurement through x‐ray fluorescence. Using as an exciting source, results are reported from a leg phantom simulating measurement of lead in a human tibia. For high activity and low activity sources, measurement results are reported for both the cloverleaf system and a conventional single detector system of equivalent surface area . The mean uncertainty and reproducibility of measurement were both significantly improved for the cloverleaf system with a high activity source. When using a source activity of , measurement of the phantom resulted in an average bone lead uncertainty of and a reproducibility of . These results represent the highest precision yet reported from a bone lead x‐ray fluorescence system.
