在放射治療技術上,一般皆以照野片( p o r t a l film ) 來確認治療位置及驗證製作的遮擋鉛塊對重要器官和腫瘤外正常組織的保護情形。但照野片的品質,常不能滿足精確的要求。 本科現擁有T h e rat ro n 7 80 c 鉛六十遠隔治療機及Toshiba L X -4 0A 模綴攝影機。但To shi b a LX4日A 原廠所附之擋影托盤與治療機STD (so u rce - t ray- d ist a nce) 及擋塊托盤( b lock tra y) 大小不符。故設計訂製符合需要的擋影托盤,並測量其準確性,發現STD與原設計短少。4 cm 。故於等中心軸SAD (source-axis-distance) 8 日cm 處﹒ 造成底片上擋塊陰影較實際約放大0 . 8% 。 將製作好的擋塊, 直接置於模擬領影機的擋影托盤下確認, 有以下優點: ( I) 擋塊位置易確認。即使有微小誤差, 皆清晰可辨。( 2 ) 患者可減少因擋塊製作錯誤,而重覆I!~野片的輻射暴露。( 3 )確保治療品質。( 4 ) 操作方便。
The prim ary purpose of portal film is to ver ify the treat ment volume and shielding block positi on under the act ual condition of treatment. However , the quality of portal film is rare ly satisfacto ry. We have a Theratron 780c Co-60 teleth er apy machine and a Toshiba LX-40A simulato r in our department. However, the orgina l specification of the size and STD (source-tray-distance) of the shadow tray in the simulato r ar e to tally differ ent from those of the Co-60 unit. There fore we have to modify the shadow tra y to mak e it suita ble to our daily practice. The STD of the modified shadow tray is only 0.4 cm shorte r than our original design. This result in about 0.8% magnifying imaging of block shadow on films in the position of SAD=80 cm. Wit h the use of the modified shadow tray, we can veri fy the shielding block in the simulator directly with the following adva ntages: (1) clea r anatomical field boundaries to prevent geographic marginal miss . (2) the avo idance of the repeat portal films due to wrong position of shielding block.(3) therapeutic quality assurance. (4) user -friendly.
