Stereotactic radiosurgery (SRS) has been well received by the neurosurgical community since its introduction in India. Knowledgeable radiosurgeons and visionary neurosurgeons have contributed to its success. At present, we have five functional and busy gamma knife centers, one proton radiosurgery center, and seven CyberKnife centers in India. However, there is a need for more such centers and formal training facilities, especially in the unorganized private sector. Radiosurgery has expanded its horizon from its initial indications of vascular and benign disorders to functional ailments and metastasis. Here, we take a look at the seminal points in its development in India along with the centers of excellence that contributed to the same. While we have tried to cover all the facets of its development, it is natural to miss some undocumented events not available in public domain. Nonetheless, the future of radiosurgery seems promising in India with the assurance of minimally invasive, safe, and effective treatment delivery.

印度放射外科的历史和演变：实力更上一层楼。

自从在印度推出以来，立体定向放射外科 (SRS) 一直受到神经外科界的好评。知识渊博的放射外科医生和有远见的神经外科医生为其成功做出了贡献。目前，我们在印度拥有五个正常运转的伽玛刀中心、一个质子放射外科中心和七个射波刀中心。然而，需要更多这样的中心和正规培训设施，尤其是在无组织的私营部门。放射外科已将其视野从最初的血管和良性疾病适应症扩展到功能性疾病和转移。在这里，我们来看看其在印度发展的开创性要点以及为此做出贡献的卓越中心。虽然我们试图涵盖其发展的所有方面，错过一些在公共领域不可用的未记录事件是很自然的。尽管如此，在保证微创、安全和有效的治疗交付的情况下，印度放射外科的未来似乎充满希望。
