Monte Carlo dose in a prosthesis phantom based on exact geometry vs streak artefact contaminated CT data as benchmarked against Gafchromic film measurements

•Effect of CT metal artefacts on MC dose in a pelvic prosthesis phantom is studied.•15 MeV electron and 10 MV photon therapy beams were used.•An artefact-free phantom model with exactly known materials was reconstructed.•For unilateral hip Ti implant, metal artefacts could cause dose errors of about...
