目的 估算和比较鼻咽癌患者在调强放疗和常规放疗过程中所受的辐射当量剂量.方法 使用热释光剂量仪对鼻咽癌患者在调强放疗和常规放疗过程中所受的周边剂量进行了测量,并推算出了患者全身当量剂量.结果 鼻咽癌患者靶区剂量给予70 Gy时调强放疗加速器的平均输出量为25235 MU,患者所受全身当量剂量为73.65 mSv;常规放疗加速器的平均输出量为8575 MU,患者所受全身当量剂量为15.28 mSv.结论 鼻咽癌调强放疗患者所受当量剂量高于常规放疗4.8倍.
目的 估算和比較鼻嚥癌患者在調彊放療和常規放療過程中所受的輻射噹量劑量.方法 使用熱釋光劑量儀對鼻嚥癌患者在調彊放療和常規放療過程中所受的週邊劑量進行瞭測量,併推算齣瞭患者全身噹量劑量.結果 鼻嚥癌患者靶區劑量給予70 Gy時調彊放療加速器的平均輸齣量為25235 MU,患者所受全身噹量劑量為73.65 mSv;常規放療加速器的平均輸齣量為8575 MU,患者所受全身噹量劑量為15.28 mSv.結論 鼻嚥癌調彊放療患者所受噹量劑量高于常規放療4.8倍.

Objective To estimate and compare the equivalent dose between the intensity modula-ted radiotherapy (IMRT) and conventional radiotherapy (CR) for patients with nasopharyngeal carcinoma (NPC). Methods The peripheral equivalent dose of NPC patients was measured by TLD during IMRT and CR. The whole-body equivalent dose was calculated. Results When prescribed tumor dose of 70 Gy was given, the mean number of accelerator output units were 25235 MU and 8575 MU, and the whole-body e-quivalent dose were 73.65 mSy and 15.28 mSy for IMRT and CR, respectively. Conclusion The equiva-lent dose in IMRT is 4.8 times higher than that in CR for patients with nasopharyngeal carcinoma.
