Proton radiography has applications in patient alignment and verification procedures for proton beam radiation therapy. In this paper, we report an experiment which used 200 MeV protons to generate proton energy-loss and scattering radiographs of a hand phantom. The experiment used the first-generation proton computed tomography (CT) scanner prototype, which was installed on the research beam line...
Proton radiography generates two-dimensional projection images of an object and has applications in patient alignment and verification procedures in preparation for proton beam radiation therapy. The quality of the image, both contrast and spatial resolution, is likely to be affected by the energy of the protons used in the creation of the radiograph, as well as by multiple Coulomb scattering and...
We report on the development of a range counter to be used in a new head scanner developed for proton Computed Tomography (pCT) in support of proton therapy treatment planning. The scanner consists of two silicon telescopes which track the proton before and after the phantom/patient, and an energy detector which measures the residual energy or range of the proton to reconstruct the Water Equivalent...
