Combination of Photon-Integrating/Counting Detector Moduli for Spectral CT

Spectral computed tomography (CT) systems are a critical diagnostic tool in medicine. CT machines use computerized x-ray imaging to produce cross-sectional images of the body. Improvements in CT imaging technologies can lower radiation exposure and support life-saving interventions. Current spectral systems can be expensive to implement and may provide only nominal information about an object’s material composition and Color. Ge Wang developed a combination detector that uses both photon integration and photon counting techniques to optimize Spectral CT to minimize patient radiation exposure while creating optimized imagery. The concept uses photon-counting elements to count photons within a window and outside a dynamically-changing window defined by thresholds during a scanning process.
