Evaluation of the reliability of markerless tumor tracking with single-energy and dual-energy imaging using machine learning [0.03%]
基于机器学习的单能量和双能量成像无标记肿瘤跟踪可靠性的评估研究
Ha Nguyen,Jason Luce,Liangjia Zhu et al.
Ha Nguyen et al.
Background: Markerless tumor tracking (MTT) using single-energy (SE) kilovoltage (kV) imaging has been proposed as a technique for lung tumor motion management. However, bony structures can obscure the tumor and make trac...
