人类对于恶性肿瘤,应用放射治疗的历史虽然并不很长,然而随着临床肿瘤学、放射物理学和放射生物学的进展,本世纪初期的放射治疗技术已迅速发展为一门新的独立学科——放射肿瘤学(RadiationOncolgy)。它有其自身的基础,专门的设备和独特的专业技术。在癌症的治疗学中正发挥着越来越重要的作用。这是无可置疑的事实。 知识的发展并非是线性延伸,而是有如长青之树不断生着许多新的分支,形成越来越多的边缘学科和 Although the history of the application of radiation therapy for malignant tumors is not very long, with the development of clinical oncology, radiophysics, and radiobiology, the early radiation therapy technology of this century has rapidly developed into a new independent discipline. - Radiation Oncolgy. It has its own foundation, specialized equipment and unique expertise. It is playing an increasingly important role in the treatment of cancer. This is an undeniable fact. The development of knowledge is not a linear extension. It is like an evergreen tree that has many new branches and forms more and more marginal disciplines.
