Since 1998 to 2002, a new clinical trial of an intraoperative boron neutron capture therapy (IOBNCT) at JRR-4 of Japan Atomic Energy Institute (JAERI) using BSH with mixed thermal/epithermal neutron beam has been accomplished. There have been 9 patients included in this study. The median survival time (MST) in GBM was 19.8 months and 16.8 months in AA. IOBNCT with mixed thermal/epithermal neutron beam provide better primary radiation effect than conventional therapy in selected cases. Our phase I/II clinical trial was effective in local tumor control. Further clinical trial with new design should be performed to prove the efficacy of IOBNCT.

We present the performance results using this new ETCC such as the imaging test using F-18 in point-like and rod-like phantoms with varying the intense of radiation. In addition, the measurementof Tc-95m which is produced by Japan Atomic Energy Agency was performed. Tc-95m emitsthe $$gamma$$-rays with the energy, 204, 583, and 835 keV, and then an image with multi-energies is examined. The position resolution achieves less than about 8 degrees from 10 degrees at 511 keV by this improvement. Further improvement of the angular resolution (position resolution) will be presented until 2015 spring. Also, we are developing the next ETCC by increasing the thickness of the scintillator from 1 rad. to 2 rad. and the gas pressure from 1 atm to 3 atm which improvethe detection efficiency by a factor of $$>$$ 5 at 511 keV. By these improvements, the imaging time of mouse is expected to be reduced from several hours with to $$<$$20 minutes for lots of kinds of RIs with the energy band from 0.1-2 MeV.
