Portal imaging with proton treatment beam is of important for quality assurance of proton therapy. It is also a direct method for in-vivo measurement of proton stopping power, which allows accurate estimation of proton range. We are developing a novel proton imager which can be used for proton QA, proton radiography and proton CT.
