The objective is to obtain a respiratory induction apparatus and a particle beam therapy system in which respiration can appropriately be induced by accurately evaluating the respiration. There are provided a respiratory induction control unit (7cC) that generates a desired respiratory signal (Rtj(t)) for respiratory induction a real respiration measurement unit (7a) that outputs a real respiratory signal (Rrl(t)) obtained by measuring real respiration of a patient and a respiration evaluation unit (7cE) in which by, as a unit, utilizing data of a single period (Tres) of the desired respiratory signal (Rtj(t)), there is calculated a pair of coefficients (a1and b1), of trigonometric functions, which correspond to the 1st-order terms by means of Fourier series expansion of data of the desired respiratory signal (Rtj(t)) and data of the real respiratory signal (Rrl(t)), which is acquired in synchronization with the data of the desired respiratory signal (Rtj(t)), and there are performed comparisons between the respective gains (Gtjand Grl) and between the respective phases (Φtjand Φrl), which are obtained from the coefficients (a1and b1), so that there is evaluated a misalignment of the real respiration from the desired respiratory signal.本發明之課題是以獲得一種藉由正確地評估呼吸而可適當地引導呼吸之呼吸引導裝置及粒子線治療裝置為目的。本發明之呼吸導引裝置係具備有:呼吸引導控制部(7cC),用來產生呼吸引導用之目標呼吸信號(Rtj(t));實呼吸測定部(7a),用來輸出測定患者之實呼吸之實呼吸信號(Rrl(t));呼吸評估部(7cE),以目標呼吸信號(Rtj(t))之1個週期(Tres)作為單位,計算一種三角函數之係數(a1,b1),該三角函數之係數為與分別對上述目標呼吸信號(Rtj(t))以及與上述目標呼吸信號(Rtj(t))同步收集之上述實呼吸信號(Rrl(t))進行傅立葉級數展開時之一次項相當而成對者,並比較從係數(a1,b1)求得之增益(Gtj,Grl)與相位(ψtj,ψrl)進行比較,以評估實呼吸對於目標呼吸信號之偏移;以及修正資訊產生部(7cE3),根據呼吸評估部(7cE)之評估結果,產生用來修正實呼吸之偏移的修正資訊(Imd)。1...加速器4...控制系統5...前段加速器6A、6B...治療室7A、7B...呼吸引導裝置7a...同步呼吸感測器7b...呼吸資訊教導裝置7c...呼吸引導裝置本體11...真空導管12射入裝置13a、13b、13c、13d...偏向電磁鐵14a、14b、14c、14d...收斂用電磁鐵15...高頻加速器空洞16...射出裝置17...六極電磁鐵21A、21B...照射裝置31A...治療室A用導管31B...治療室B用導管31m...主導管32...切換電磁鐵(切換裝置)33、33G...偏向電磁鐵40...全體控制部41...加速器控制部42...照射系統控制部43...輸送系統控制部
