Conception of Stereotactic Radiosurgery in Stockholm
Lars Leksell at the Karolinska Institute conceived stereotactic radiosurgery and with collaborators developed the Gamma Knife concept and prototype in the 1960s and the first clinical installations in Stockholm demonstrated that focused radiation could create precise intracranial lesions without open surgery
Clinical Applications and Evolution
Gamma Knife radiosurgery provided a minimally invasive option for treating small intracranial targets such as arteriovenous malformations and selected tumors and over time improvements in imaging guidance planning and dose delivery expanded indications and improved outcomes
Integration with Imaging and Neurosurgery
The success of radiosurgery depended on high quality imaging for target definition and on stereotactic frames and planning systems and the technology fostered close collaboration between neurosurgery and radiology and influenced the development of other focused radiation platforms
