Abstract

Background and purpose

In lung cancer patients, accuracy in contouring is hampered by image artefacts introduced by respiratory motion. With the widespread introduction of 4DCT there is additional uncertainty caused by the use of different reconstruction techniques which will influence contour definition. This work aims to assess both inter- and intra-observer contour variation on average and motion compensated (mid-position) reconstructions.
