Linear accelerator-based radiosurgery has advanced significantly, requiring stringent technical and clinical precision. Successful outcomes depend on collaborative efforts from neurosurgeons, radiation oncologists, and medical physicists.

Area of Science:

  • Medical Physics
  • Neurosurgery
  • Radiation Oncology

Background:

  • Radiosurgery has evolved over decades, initially limited to specialized centers.
  • Advances in linear accelerator (LINAC)-based techniques and imaging in the 1980s spurred widespread interest and adoption.
  • LINAC-based radiosurgery presents more demanding technical and clinical requirements than standard radiotherapy due to smaller target volumes and single-session dosing.

Purpose of the Study:

  • To highlight the evolution and increasing adoption of linear accelerator-based radiosurgery.
  • To emphasize the stringent requirements and collaborative nature of modern radiosurgery.
  • To outline the roles of various medical professionals in radiosurgery procedures.

Main Methods:

  • Review of the historical development and current practices of radiosurgery.

Related Experiment Videos

  • Discussion of technical and clinical considerations for LINAC-based radiosurgery.
  • Analysis of the multidisciplinary team approach in radiosurgery.

    • Main Results:

    • Radiosurgery, particularly LINAC-based, is now offered by most major radiotherapy centers.
    • Accurate radiosurgery demands higher precision than conventional radiotherapy.
    • Successful radiosurgery relies on close collaboration among neurosurgeons, radiation oncologists, neuroradiologists, and medical physicists.

    Conclusions:

    • Linear accelerator-based radiosurgery expands the capabilities of radiotherapy departments.
    • Neurosurgeons play a key role in target definition, while radiotherapists determine dose and isodose selection.
    • Effective radiosurgery is a complex, team-based endeavor, with physics underpinning all stages from localization to dose delivery.
