Table 2: Mean respiratory data and tumor motion amplitudes for patients under abdominal compression as observed in 4D-CT data and averaged with respect to lung lobe location(Δx: medial/lateral; Δy: anterior/posterior; Δz: superior/inferior; std: standard deviation). The last row (*) gives the results if all the patients are analyzed as a single group ignoring tumor’ spatial location in different lung lobes.
