Iterative method for elimination of the Kbeta filter in dual-beam differential tissue absorptiometry.


The application of a dual photon beam to the measurement of tissue and tissue-like substances has generally required the use of a filter to attain the required monochromaticity of the lower-energy x-ray photons. In many cases this has the undesirable effect of also severely attenuating the desired low-energy beam. A method for circumventing the use of the… (More)
