Accuracy of Photon Dose Calculation on Photon-Counting Computed Tomography—A Comparison Study Based on Virtual Monoenergetic and Electron Density (Rho) Images for Pancreatic Cases
The results demonstrated good agreement in dose calculation between 70 keV VMI and Rho images. For regions with iodine contrast, Rho images provided by PCCT can suppress the contrast enhancement, thereby mitigating unnecessary uncertainties. This benchmark performance shows that PCCT can be safely used for dose calculation with certain advantages, making it a valuable alternative for RT treatment planning.
