Outline of Final Research Achievements

Boron Neutron Capture Therapy (BNCT) is a new cancer therapy. Now it is in a phase of clinical test. Though this is a very much promising cancer treatment, there are some unsolved problems. One of them is that the treatment effect cannot be known in real time. In this study, a CdTe semiconductor detector was used to realize a SPECT system for BNCT. By measuring emitted gamma-rays via boron neutron capture reaction in real time, a three dimensional image of BNCT treatment can be obtained by using a SPECT technology. Basic theoretical studies for it were carried out and basic requirements were made clear. And basic performance of one and two CdTe element devices was examined to confirm the validity of the CdTe detector system. In future, an array-type CdTe detector for BNCT-SPECT would be expected.
