目的　通過非小細胞肺癌（NSCLC）圖像引導放射治療（IGRT）過程中，每次治療前獲取的錐形束CT圖像，動態觀察腫瘤體積的變化。方法　2009年2月－2010年8月18例周圍型NSCLC患者接受IGRT。每次治療前進行千伏級錐形束CT（KV-CBCT）圖像的采集。每周在KV-CBCT圖像上勾畫腫瘤靶區并計算靶區體積，經統計后分析腫瘤治療過程中體積的變化。結果　治療開始時平均體積為28.5 cm3（2.5～109.1 cm3），治療結束時平均體積為17.1 cm3 （1.4～73.4 cm3）。平均退縮率為35.9%（3.9%～68.9%），平均每天的退縮率為1.5% （0.1%～5.4%）。治療結束時，0例病灶完全消退，1例部分消退，10例微小消退，7例穩定。結論　治療過程中，NSCLC腫瘤的退縮可以通過KV-CBCT進行觀察。當病灶為周圍型時，能對腫瘤體積的變化進行客觀有效的評價。放射治療過程中腫瘤的體積改變具有很大的異質性，腫瘤在治療過程中體積均有一定的退縮，但治療結束時大多數病灶僅為微小消退或穩定。
