In his director's greeting he describes the advantages of heavy-ion therapy over conventional X-ray treatment in dose concentration and biological effectiveness, with courses typically completed within one to four weeks, and the centre's roles in training specialists and promoting international collaboration. He has published extensively on carbon-ion radiotherapy from the Gunma facility.","asOf":"2026-09-10","links":[{"label":"Source: GHMC director's greeting","url":"https://heavy-ion.showa.gunma-u.ac.jp/page.php?id=15"}],"tags":["leadership","clinician-scientist","radiotherapy","particle-therapy"],"related":[],"cancers":[],"sections":[],"technologies":[],"targets":[],"drugs":[],"companies":[],"institutions":["gunma-heavy-ion-medical-center"],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":["cancers-mdpi"],"dependsOn":[],"notes":[],"role":"Director of the Gunma University Heavy Ion Medical Center","institutionId":"gunma-heavy-ion-medical-center","specialisms":["Carbon-ion radiotherapy","Radiation oncology","Particle therapy"],"profiles":[{"label":"Institution profile","url":"https://heavy-ion.showa.gunma-u.ac.jp/page.php?id=15"},{"label":"PubMed","url":"https://pubmed.ncbi.nlm.nih.gov/?term=Ohno+T%5BAuthor%5D+carbon+ion+Gunma"}],"papers":[{"title":"Carbon Ion Radiotherapy at the Gunma University Heavy Ion Medical Center: New Facility Set-up","journal":"Cancers","year":2011,"doi":"10.3390/cancers3044046"},{"title":"Particle radiotherapy with carbon ion beams","journal":"EPMA Journal","year":2013,"doi":"10.1186/1878-5085-4-9"},{"title":"Efficacy and Safety of 4 Fractions of Carbon-Ion Radiation Therapy for Hepatocellular Carcinoma: A Prospective Study","journal":"Liver Cancer","year":2021,"doi":"10.1159/000520277"}],"orcid":"0000-0002-6703-3144"},"route":"/people/tatsuya-ohno/","neighbours":{"institution":[{"id":"gunma-heavy-ion-medical-center","kind":"institution","name":"Gunma University Heavy Ion Medical Center","route":"/institutions/gunma-heavy-ion-medical-center/"}],"journal":[{"id":"cancers-mdpi","kind":"journal","name":"Cancers","route":"/journals/cancers-mdpi/"}]}}
