Photon-counting-detector (PCD) CT acquires multi-energy data in a single scan, enabling quantitation of electron density (ρe) and effective atomic number (Zeff). This study assessed the performance of PCD-CT for ρe and Zeff mapping across different phantom si...

Stopping-Power Ratio Accuracy for Proton Therapy: Photon-Counting Detector Versus Energy-Integrating Detector CT
Stopping-power ratio (SPR) is used in proton therapy to calculate the radiation dose distributions. SPR depends on tissue composition and can be calculated using multi-energy CT. This study compares the accuracy of SPR calculated using energy-integrating dete...

Enhancing Lung Tumor Visibility on 2D X-Ray Imaging Utilizing Prior CT Information
Lung tumors are poorly visible on conventional on-board 2D X-ray imaging due to limited soft-tissue contrast and overlapping anatomy, posing a challenge for patient setup on proton therapy systems equipped with 2D X-ray imaging. Our goal is to develop a novel...
