Abstract
The superficial neck nodes in only 1 out of 7 patients with head and neck cancer studied received more than 90% of the prescribed dose when treated with opposed 6 MV photons. Beam spoilers placed upstream from the patient enhanced the dose to the superficial node at the expense of higher dose to the skin.
摘要
在接受对头照射6兆伏光子治疗的7例头颈癌患者中，只有1例患者颈部浅表淋巴结接受的剂量超过了处方剂量的90%。置于患者身体上游的射野均整器提高了浅表淋巴结的剂量，但代价是皮肤剂量更高。
