About

Hiroshi Onishi is a leading figure in radiation oncology, whose research is centered on precision radiotherapy techniques and the management of oligometastatic disease. His work has significantly advanced the clinical application of stereotactic body radiotherapy (SBRT) for treating lymph node oligometastases, offering a non-invasive option for patients with limited metastatic spread. A major contribution to the field is his pioneering evaluation of surface-guided radiotherapy (SGRT) systems, particularly through his landmark phantom study on VOXELAN. This work, which has garnered 9 citations, established critical benchmarks for the detection accuracy of 3D body scanners across various treatment sites, directly improving the safety and precision of patient set-up in daily clinical practice. By systematically validating these technologies, Onishi has helped bridge the gap between emerging SGRT tools and their reliable implementation in the clinic. His research is essential reading for physicists and clinicians seeking to enhance treatment accuracy and reduce radiation errors, marking him as a key contributor to the evolution of modern, image-guided radiation therapy.
