By means of an electronic computer various standard technics of irradiation for cancer of the middle esophagus are compared as to the basic dosimetry range with the schedule of irradiation, calculated according to the program of the optimum dosimetry level. The criterion of the optimum dosimetry level was the requirement of a minimum integral dose in patient's body under even irradiation of the tumor zone (circular area with a diameter of 6 cm) but not less than 80% of the dosage in the esophagus center. The technics under stude show that rotation irradiation through 360 degrees provide the nearest approximation to the optimum regime.
借助电子计算机，根据最佳剂量测定水平程序计算出的照射时间表，对中段食管癌的各种标准照射技术在基本剂量测定范围方面进行了比较。最佳剂量测定水平的标准是，在肿瘤区域（直径6厘米的圆形区域）均匀照射下，患者体内的积分剂量要最小，但食管中心的剂量不得低于80%。所研究的技术表明，360度旋转照射最接近最佳照射方案。
