Abstract

Respiration-related variations in the distance between the center of mass of gross tumor volume and both esophagus and spinal cord in the transversal plane were on average 3mm (range 1-10mm) and 2mm (range 1-5mm), respectively. Depending on the tumor location and treatment technique, variations might become important for treatment planning.
