Rate My Professor Seishin Takao

Seishin Takao serves as Associate Professor in Radiation Medical Physics at Hokkaido University. He received his Ph.D. in Engineering from the Graduate School of Engineering at Hokkaido University in 2009 and holds a license as a medical physicist. His research field and educational field are medical physics, with a primary research topic of proton therapy.

Recently, with the background of improved treatment outcomes due to the advance of medical science and engineering, the needs for radiation treatment have rapidly increased. Particularly, particle beam therapy that applies particle accelerators to medical treatment has been welcomed for its ability to minimize the physical burden on patients by concentrating the delivered doses on the cancer lesion. In addition, recent use of image-guided radiation therapy has enabled treatments that incorporate features of biological response and changes in tumor shapes and movement of patients during treatment. He has conducted research to applying radiation physics, quantum beam applied engineering, and image engineering to practical clinical settings in collaboration with the Proton Beam Therapy Center, Hokkaido University Hospital and Division of Quantum Science and Engineering, Faculty of Engineering. Research themes include dual-source cone beam CT imaging on the rotating gantry of proton beam therapy system and knowledge-based DVH prediction method for proton therapy. Key publications include “Intrafractional baseline shift/drift of lung tumor motion during gated radiotherapy with a real-time tumor-tracking system” in International Journal of Radiation Oncology Biology Physics (2016), “A simulation study on the dosimetric benefit of real-time motion compensation in spot-scanning proton therapy for prostate” in Journal of Radiation Research (2017), and “Selection of external beam radiotherapy approaches for precise and accurate cancer treatment” in Journal of Radiation Research (2018). He received the Basic Science Abstract Award at the American Society for Radiation Oncology 55th Annual meeting in 2013.
