Professor Hiroki Shirato of Hokkaido University, Japan, is Director of the Global Station for Quantum Medical Science and Engineering (GSQ); a research hub that is facilitating innovative collaborative studies. GSQ is part of the Proton Beam Therapy Center (PBT Center), of which Shirato is also Director. The leading research unit at Hokkaido University is collaborating with the Radiation Oncology Department of Stanford University School of Medicine in the US, which is headed up by Professor Quynh-Thu Le. This collaboration is part of the remit of GSQ and is set to make the Global Station the most innovative research hub on radiation therapy in the world. The work that Shirato is currently focused on is exploring how proton beams can improve cancer treatment. He provides an insight into some of the work that is underway: "We are working on a reverse translational study about real-time tumour tracking technology. We have adapted the real-time tracking technology to the animal experiment and found important scientific findings," he explains. "In another line of work, we are trying to find a precise way of selecting an appropriate external beam radiotherapy for each patient by using a biological model. Since there are so many biological models in the world, we are trying to establish an international standard.
