Welcome Message from PTCOG 56 Conference Chairs

On behalf of the Organizing Committee, we are pleased to announce that the 56th Annual Conference of the Particle Therapy Co-operative Group (PTCOG56) will take place Monday, May 8 through Saturday, May 13, 2017 at the Makuhari Messe (Chiba Prefecture) and Pacifico Yokohama (Kanagawa Prefecture) in Japan. We are working hard to prepare a conference agenda focused on educational workshops and scientific meetings that will be meaningful and productive for all involved in the field of particle radiotherapy.

The main theme of PTCOG56 is "Ion-beam Radiotherapy in the 21st Century: Accuracy and Efficacy"
In recent years, the number of facilities dedicated to particle radiotherapy has been on the upswing throughout the world. Japan is no exception; today, five of the world’s 10 carbon-ion radiotherapy facilities are in operation in the country.

Since 1994, one of these, the National Institute of Radiological Sciences (NIRS), has conducted numerous clinical and research studies on the latest advances in the field. On the first day of the conference, an expedition to NIRS to observe a rotating gantry using high-temperature superconducting magnets will be offered. On the last day of the conference, you will have the opportunity to tour the ion-beam Radiation Oncology Center in Kanagawa (i-ROCK), which specializes in a scanning irradiation method using four in-room computed tomography units.

Early May is one of the most wonderful times of the year to visit Japan. From Yokahama, you can embark on an enjoyable day trip to the historic cities of Kamakura and Hakone, which is famous for its hot springs. We also will be hosting a Gala Dinner at the Yokohama Museum of Art; it is very close to the conference venue and you will have the opportunity to enjoy its many works of fine art before dining.
We very much look forward to your participation.
