(a) Patient 7 had increased fluid in his affected lung (pleural effusion), which impacted inter-fraction stability of the tumor throughout treatment. This patient also had the largest systematic error in the study population, emphasizing the importance of image-guided adaptive radiotherapy. (b) For Patient 7, change in daily tidal volume with respect to change in gross tumor volume size over treatment.
