16th ICNCT Helsinki, Finland 2014.06.19 Development of treatment couch with computer controlled 5-axis movements - For clinical use in the accelerator-based BNCT - 　Thank you　( chairperson / Dr.TANAKA / Prof. TANAKA ).　（議長 / 田中博士/ 田中教授に御礼の言葉）   　Today, I‘d like to talk to you about　「Development of treatment couch」 .　（講演題目の説明、紹介） 　｢I'd like ～は、～させて頂くという表現｣ 　At the beginning, I'd like to show you the contents my presentation.　（プレゼン内容の事前説明） For clinical use in the accelerator-based BNCT Yoshihisa Abe1, Masashi Ito1, Ryo Fujii2, Masaru Nakamura2, Yoshio Imahori2, Jun Itami1  1 Department of Radiation Oncology, National Cancer Center, 2 Department of R&D, Cancer Intelligence Care Systems, Inc. 16th ICNCT　　　　　　　　　　 Helsinki, Finland 　　2014.06.19

National Cancer Center (Tokyo) started a joint research with CICS in Dec. 2010 and is planning the installation of the accelerator-based BNCT system. New building for BNCT was finished in Dec. 2013 and accelerator installation is expected in summer this year. NCC New Building

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. B1F ; Accelerator room B2F ; Treatment room Vertical Beam Line NCC New Building

NCC New Building Fix type Vertical Beam Line You can see Proton accelerator . Target shielding system. It’s a closed position . And opened . Now continue to setting . Look like So Heavy. Fix type Vertical Beam Line NCC New Building

NCC New Building Covered leaf design . It may be feel refreshing air of forest . Like a JUKOLAN VIESTI（ユコラ リレー） NCC New Building

NCC New Building Fix type Vertical Beam Line The automatic-reproduction 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 . NCC New Building

Treatment couch with computer controlled 5-axis movements Construction of this treatment couch is 3 parts components . a stretcher move between CT room and BNCT treatment room . Treatment couch with computer controlled 5-axis movements

Treatment couch with computer controlled 5-axis movements Computer controlled 5-axis movements base in treatment room. Carbon fiver table top with vacuum fix . Treatment couch with computer controlled 5-axis movements

System Block CT image data tumor contour Position data file y - axis CT room tumor contour Positioning laser system Position data file Treatment room y - axis z - axis 1st step : Send to Optimization system CT image with contour from CT via treatment support software . Optimization system x - axis 5-axis movements couch

Tumor area / Treatment angle Optimization system calculation Rotation angle and Tilt angle . 平均depthを最小にする。最大depthを6ｃｍ以下にする。 Tumor average depth and maximum depth . Make a position to less than 6cm . Tumor area / Treatment angle

System Block CT image data tumor contour Position data file y - axis CT room tumor contour Positioning laser system Position data file Treatment room y - axis z - axis 3rd step : Send to positioning laser system from Optimization system . Move a laser parts for treatment position mark . Optimization system x - axis 5-axis movements couch

Pretreatment marks Celling and both side wall laser parts is movable . Make sure of treatment position marks.

Conclusion Laser marks BNCT Head tumor CT room （株）アドイン研究所 Conclusion レーザーポインタ Table top Laser marks BNCT Head tumor 天板 CT room Rotation angle Tilt angle Long and lateral movement is automaticity. Vertical axis movement is manually-operated . 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. Development of clinically applicable treatment couch for BNCT was successfully accomplished. Treatment room
