  1. Abbreviations: ADC adenocarcinoma, Meta metastasis, SD standard deviation, SCC squamous cell carcinoma, SP supine, PR prone, GTV gross tumor volume, COM 3-dimensional displacement of center of mass.
  2. GTV-COM was calculated at the peak 3D distance using 4DCT data sets for all respiratory phases (10 phases) and the 3 phases around peri-exhalation for the ungated and gated strategies, respectively.
