Abstract
We studied the use of internal anatomical surrogates (carina and diaphragm) for the purpose of predicting the 3D position of lung tumours in 41 patients, in whom repeat 4DCT scans were available. Despite using two surrogates, significant prediction errors were observed, which varied depending on tumour position, baseline tumour motion and respiratory phase.
