Correlation of ACTA Scanner Number with Electron Density.

Abstract

The report demonstrates that the numbers generated by computerized axial-transverse tomography devices, which are proportional to x-ray attenuation coefficients, correlate with electron density in low-Z biological materials rather than with mass density. For high-Z materials, where the photoelectric cross section is appreciable, the correlation is with the density of high-Z atoms.
