张矩怀教授在肿瘤分级和放射治疗上成绩显著。此次他在北京参加我国第一次放射治疗学术会议后,曾在北京、西安、福州举行学术讲座介绍美国放射治疗学现状。目前美国对肿瘤治疗除少量瘤种外仍以手术切除和放射治疗为主,美国自50年代开始迅速淘汰<200KV 的治疗机而代以>1000KV 的直线加速器。在改善放疗机的性能上还使用neutrons 和 Pimesons 放疗机的,但为数甚少。据美国政府1970年官方统计资料说明,自使
Professor Zhang Moihuai has achieved remarkable results in tumor grading and radiotherapy. After attending China’s first radiotherapy academic conference in Beijing, he held academic lectures in Beijing, Xi’an, and Fuzhou to introduce the status of radiotherapy in the United States. At present, in the United States, except for a small number of tumors, surgical resection and radiotherapy are the main methods for tumor treatment in the United States. In the United States, since the 50s, the 200KV treatment machine has rapidly been eliminated and a linear accelerator of >1000KV has been substituted. Neutrons and Pimesons radiotherapy machines have also been used to improve the performance of radiotherapy machines, but there are few. According to the official statistics of the U.S. government in 1970,
