Further Improvements of XRF Analysis of Cadmium In Vivo

Although clinically useful, current equipment and methods for X-ray fluorescence (XRF) analysis in vivo should be improved in order co: 1) obtain better detectability of heavy elements, and thus extend the measurements to new groups of persons and to new elements, 2) make the equipment transportable and easier to handle in busy work-places or as bedside instruments at hospitals when seriously ill patients are to be examined. The stepwise introduction of new instruments and methods for in vivo XRF analysis has resulted in considerable improvements of the detectability for some elements but not for others.
