Submillimetre structures of lung tissue are not represented in CT images used for radiotherapeutic dose calculation. In order to study the effect experimentally, lung substitutes with properties similar to lung tissue were chosen, namely two types of commercial lung tissue equivalent plates (LTEP) (CIRS, USA), two types of cork, balsawood, floral foam and konjac sponge. Laterally integrated dose profiles were measured as a function of depth (IDD) for proton pencil beams (P with an initial nominal energy of 97.4 and 148.2 MeV, respec
