Description

The use of protons or other heavy charged particles instead of X-rays in computed tomography (CT) is explored. The results of an experimental implementation of proton CT are presented. High quality CT reconstructions are obtained at an average dose reduction factor compared with an EMI 5005 X-ray scanner of 10:1 for a 30-cm-diameter phantom and 3.5:1 for a 20-cm diameter. The spatial resolution is limited by multiple Coulomb scattering to about 3.7 mm FWHM. Further studies are planned in which proton and X-ray images of fresh specimens will be compared. Design considerations indicate that a clinically useful proton CT scanner is eminently feasible. (Auth.)
