Description
Proton computed tomography (pCT) offers an alternative to x-ray imaging with potential for three dimensional imaging, reduced radiation exposure, and in-situ imaging. The second generation pCT system being developed at Northern Illinois University in collaboration with Fermilab and Delhi University is comprised of a tracking system, a calorimeter or the range detector, data acquisition system, a computing farm, and software algorithms for image reconstruction. The proton beam encounters the upstream tracking detectors, the patient or phantom, the downstream tracking detectors, and a calorimeter. The tracking detectors are scintillating fibers and the calorimeter is made up of stacked scintillator plates. The data acquisition sends the proton scattering information to an offline computing farm. The pCT detector design allows for an increased data acquisition rate (up to 5 million proton tracks per second) and an improved imaging algorithm, which significantly reduced reconstruction times of three dimensional images.
In this presentation, we will present the current status of the pCT detector system, development of the complete detector simulation and reconstruction tools and their validation, and preliminary test beam data analysis with the full pCT detector system.
