We report in this presentation how we actually implemented the revision for the first time in clinical practice.\n[Methods] We followed the publication by Kanematsu et al in Phys. Medi. Biol. 61 (2016) 5037-5050 for carbon ions of effective energy 131 MeV/nucleon proposed by Inaniwa et al in Phys. Med. Biol. 61 (2016) N542-N550 to determine CT numbers and stopping-power ratios of 11 representative tissues for the conversion function of each clinical CT-scanning condition. We analyzed the range variation due to the revision for sampled treatment plans. \n[Results] The revision of the conversion caused marginal effect on the range calculation.\n[Conclusion] The transition to the revised method was straightforward and would marginally improve the range accuracy in clinical practice.
