16th ICNCT　　　　　　　　　　 Helsinki, Finland 　　

2. National Cancer Center (Tokyo) started a joint research with CICS in Dec and is planning the installation of the accelerator-based BNCT system.
New building for BNCT was finished in Dec and accelerator installation is expected in summer this year.

3. 治療時のPatient stile を優先し　supine position
地下１階に陽子加速器、地下２階にBNCT治療室を配置する設計とした。
その結果 垂直ビームラインとなった。
We precedence relax stile at treatment time , it take a supine position .
We design Accelerator room for Basement 1st floor , and Treatment room for B2F.
Our system is Vertical Beam Line.
Treatment Head is stable.
It can’t movable.

and self-repair system
We development of treatment couch with computer controlled 5-axis movements .
Generally treatment couch movement is long lateral and vertical axis .
We addition to rotation and tilt .

Construction of this treatment couch is
3 parts components .
a stretcher move between CT room and BNCT treatment room .

Because Patient safety.
Development of clinically applicable treatment couch for BNCT was successfully accomplished. However, the treatment planning information is presently input off-line and the system is not DICOM-RT-based. Additionally real-time position change is desirable. Version up of the system is already being launched.
