Low megavoltage electrons, because of their limited penetration, have been found very useful in the treatment of generalized superficial malignancies. However, because of the complexity of the human body contour, it is extremely difficult to achieve uniform dose distribution over the entire body surface. To achieve this, various techniques ranging from two to six fields have been used. In this paper, we discuss the disadvantages of these techniques and describe a new technique, "the rotation technique," which is superior.
低兆伏电子因其穿透能力有限，已被发现对治疗全身性浅表恶性肿瘤非常有用。然而，由于人体轮廓的复杂性，要在整个身体表面实现均匀的剂量分布极其困难。为了实现这一点，已经使用了从两野到六野的各种技术。在本文中，我们讨论了这些技术的缺点，并描述了一种更优越的新技术——“旋转技术”。
