摘要

本文描述目前本科有關於順形放射治療的技術細節，並報告九個病例的初步經驗。使用步驟包括：（一）姿勢設定、固定及初次模擬攝影（二）電腦斷層模擬攝影及影像取得（三）治療目標及重要器官的界定（四）射束的界定、照野的安排及劑量的計算（五）計劃的評估與比較因治療的驗證與執行等六部份。國內順形放射治療正在起步階段，目前我們徐了將更精簡整個流程步驟外，也預備擬定一些治療計劃讓適當的病人進入這項治療。

Technical details and early experiences of nine patients treated with conformal radiation therapy were described and discussed. Techniques based on CT images reconstruction and incorporating beam's eye view-assisted blocks design were used. General procedures currently apply at this department including: patient positioning, immobilization, first x-ray simulation, CT simulation and image acquisition, target and critical organ definition, beam definition, fields arrangement, dose calculation, plan evaluation, treatment verification and delivery. Technical refinement and protocol setup for conformal radiation therapy at this department are now in progress.
