摘要: Improved methods and apparatus for in vivo measurement of the skeletal lead burden a patient diagnosis toxicity are disclosed. The comprises an x-ray tube emitting soft low energy x-rays from silver anode, polarizer polarizing emitted x-rays, detector detecting photons fluoresced atoms patient's tibia upon irradiation by polarized x-rays. spectrally analyzed to determine their distribution. Peaks indicating presence identified if has relatively high bone content. data may be compared recorded with respect similar test performed on patients having also had conventional EDTA chelation tests thereon order correlate results particular conventionally accepted test.
