积极慎重地开展神经外科定向放射治疗张纪近十年来，随着微电子及放射治疗技术的发展，在神经外科领域中采用脑立体定向原理，对颅内靶点精确地进行局限性大剂量放射线照射已成为可能。从此衍生出许多新的治疗技术，如采用６０钴或直线或回旋加速器为放射源的γ刀和Ｘ刀、... Active and prudent to carry out neurosurgery directed radiotherapy Zhang Ji nearly 10 years, with the development of microelectronics and radiation therapy technology, the use of brain stereotactic in the field of neurosurgery, precise localization of intracranial target large dose radiation Irradiation has become possible. Since then, many new therapies have evolved, such as γ-knife and X-knife with 60 cobalt or linear or cyclotron radiation sources.
