PROBLEM TO BE SOLVED: To obtain a particle beam therapy device which is normally stopped in case of an earthquake.SOLUTION: A seismograph 3 which detects two earthquakes of unequal scale is prepared on an accelerator system 101. The output of this seismograph 3 is received by a stop device 4. While this stop device 4 outputs the output of the seismograph to a stop circuit 5 of an accelerator system control device and a stop circuit 6 of an illuminating system control device as stop information, and stops the accelerator system 101 and the illuminating system, a treatment table 107 at the position under treatment is returned to a fixed position before initiation of therapy. In case of a large earthquake, the stop device 4 makes a therapy cooperation server 110 transmit the patient file of a patient during therapy to a therapy cooperation server 111 of a particle radiation therapy device 112 in other areas by transmitting earthquake information to the therapy cooperation server 110.COPYRIGHT: (C)2013,JPO&INPIT【課題】地震時に正常に停止するようにした粒子線治療装置を得る。【解決手段】加速器系101に大きさの異なる二つの地震を検知する地震計3を設け、この地震計3の出力を停止装置4で受信し、この停止装置4が加速器系制御装置の停止回路5及び照射系制御装置の停止回路6へ停止情報として出力して加速器系101及び照射系を停止させると共に、治療中位置の治療台107を治療開始前の定位置に戻し、地震大の場合には、停止装置4は、治療連携サーバ110に地震情報を送信することにより、治療連携サーバ110は治療中の患者の患者ファイルを他の地域の粒子線治療装置112の治療連携サーバ111に送信するようにした。【選択図】図1
