TL;DR: A carbon beam of 80 keV/microm in the spread-out Bragg peak was found to be equivalent in biological responses to the neutron beam that is produced at cyclotron facility in National Institute Radiological Sciences (NIRS) by bombarding 30-MeV deuteron beam on beryllium target.
Journal ArticleDOI
Treatment planning for a scanned carbon beam with a modified microdosimetric kinetic model.
Taku Inaniwa,Takuji Furukawa,Yuki Kase,Naruhiro Matsufuji,Toshiyuki Toshito,Yoshitaka Matsumoto,Yoshiya Furusawa,Koji Noda +7 more
TL;DR: Good agreement between the two curves proves that the proposed method is a candidate for calculating the biological effects in treatment planning for ion irradiation.
Journal ArticleDOI
Reformulation of a clinical-dose system for carbon-ion radiotherapy treatment planning at the National Institute of Radiological Sciences, Japan.
Taku Inaniwa,Nobuyuki Kanematsu,Naruhiro Matsufuji,Tatsuaki Kanai,Toshiyuki Shirai,Koji Noda,Hiroshi Tsuji,Tadashi Kamada,Hirohiko Tsujii +8 more
TL;DR: The updated clinical-dose system reflects the physical and biological characteristics of the therapeutic C-ion beam more accurately than the original system, while at the same time allowing the continued use of the dose-fractionation protocols established with theOriginal system at NIRS.
Journal ArticleDOI
Influence of fragment reaction of relativistic heavy charged particles on heavy-ion radiotherapy
TL;DR: This investigation of the fragments' fluence and linear energy transfer (LET) spectra produced from various incident ions using an experimental approach to reveal these physical qualities of the beams revealed that the number of light fragments, such as hydrogen and helium, became larger than thenumber of primaries in the vicinity of the range end.
Journal ArticleDOI
Examination of GyE system for HIMAC carbon therapy
Tatsuaki Kanai,Naruhiro Matsufuji,Tadaaki Miyamoto,Jun-etsu Mizoe,Tadashi Kamada,Hiroshi Tsuji,Hirotoshi Kato,Masayuki Baba,Hirohiko Tsujii +8 more
TL;DR: A retrospective analysis was made to examine appropriateness in the estimation of the biologic effectiveness of carbon-ion radiotherapy using resultant data from clinical trials at the heavy-ion medical accelerator complex (HIMAC) at the National Institute of Radiological Sciences in Chiba, Japan.
