Contrast in computerized transverse axial tomography of brain

A K Drukier. Phys Med Biol. 1977 Sep.

Abstract

A study of contrast in photon transmission tomography of brain is presented. Quantitative evaluation of linear attenuation coefficients due to photo-electric, Compton and pair creation effects suggests that the use of photons of a few MeV considerably improves the contrast between white and grey brain matter. The patient dose at different photon energies is calculated.
