Abstract
A Proton Computed Tomography (pCT) system utilizing proton beams for construction of 3-dimensional density maps of both test phantoms and living tissue. PCT is a much sought-after modality for treatment planning and validation at proton therapy treatment centers, as it would allow in situ imaging with the same beam that is used for the treatment. A pCT system according to the present invention includes gaseous detectors for tracking and energy reconstruction, a shutter system to extend dynamic range features while maintaining good energy resolution, and a method for determining proton energy from a forward-search algorithm utilizing segmentation of energy detector ionization signal readout. The gaseous detectors are Gas Electron Multiplier (GEM) based gaseous detectors.
