AAPM Task Group 430 aims to comprehensively evaluate organ and effective dose (ED) estimations from whole body CT data to support recommendations for DLP-to-ED conversions factors and their associated uncertainties. Accurate whole-body organ segmentation is c...
Accurate calibration in photon-counting detectors (PCDs) for inhomogeneous pixel responses caused by charge sharing, pulse pile-up, and energy-dependent efficiency is the most critical and challenging task for PCD-based imaging applications. Conventional gain...
To evaluate the spatial resolution of an X-ray scatter imaging system utilizing a Photon Counting Detector (PCD) for real-time lung tumor tracking. Unlike transmission imaging, scatter imaging offers direct 3D tumor localization. This study quantifies the sys...
