Different irradiation techniques for therapy of para-aortic lymph nodes are compared using fixed or pendulous fields of photons with the energy 42 MeV from a 42 MeV betatron. The techniques are estimated considering the load to the radio-vulnerable contiguous organs, especially to the spinal cord and kidneys. The findings presented, being founded on measurements and on computations resulting therefrom, show that the most satisfying dose distributions are obtained by the Y-shaped three-field technique, by the combination of telecentric-excentric dorso-ventral pendulous irradiation with a ventral irradiation by fixed fields, or be means of a biaxial excentric pendulous irradiation. By examples evidence is given of the possibility of delivering a focal dose of 6000 rd or more to the tissue within a large-sized target volume, whilst the radiation load to the contiguous radiosensitive organs, i.e. spinal cord and kidneys, does not exceed the tolerance dose.
使用来自42兆电子伏电子感应加速器的能量为42兆电子伏的光子的固定或下垂野，比较用于治疗腹主动脉旁淋巴结的不同照射技术。考虑到对放射性敏感的相邻器官，特别是脊髓和肾脏的负荷，对这些技术进行评估。所呈现的研究结果基于测量以及由此产生的计算，表明通过Y形三野技术、远心-偏心背腹下垂照射与固定野腹侧照射相结合或通过双轴偏心下垂照射可获得最令人满意的剂量分布。通过实例证明了在大尺寸靶区内向组织输送6000拉德或更高的局部剂量的可能性，同时对相邻的放射敏感器官，即脊髓和肾脏的辐射负荷不超过耐受剂量。
