用10-16 MeV能量对4-31 MeV能量范围内的高能电子束剂量分布进行修正的方法，成功地应用于颊粘膜癌病例。明显的放射反应仅发生在病变区。口腔其他部位未见明显反应。治疗完成一年半后，3个皮损中有2个改善，没有发现疾病迹象。
A method to modify the dose distribution of high-energy electron beams of betatrons operating in the 4- to 31-MeV energy range was successfully applied to cases of carcinoma of the buccal mucosa, using 10- to 16-MeV energy. Marked radiation reaction occurred only in the area of the lesion. No visible reaction was seen in other parts of the oral cavity. Two of 3 lesions improved and showed no evidence of disease one and one-half years after completion of treatment.
