Summary
Stereotactic radiosurgery (SRS) uses focused radiation for intracranial targets. Recent innovations are advancing non-invasive techniques, moving beyond traditional rigid head frames for improved patient treatment.
Area of Science:
- Neurosurgery
- Radiation Oncology
- Medical Physics
Background:
- Stereotactic radiosurgery (SRS) is a precise, single-session radiation therapy targeting intracranial lesions.
- Accurate dose delivery traditionally relies on rigid stereotactic head frames for immobilization.
- Both Cobalt-60 (Gamma Knife) and linear accelerator (linac) technologies have been used for decades.
Purpose of the Study:
- To review recent technological advancements in stereotactic radiosurgery.
- To highlight innovations enabling non-invasive frame-based SRS.
- To discuss developments relevant to clinical practice.
Main Methods:
- Review of recent literature on stereotactic radiosurgery technologies.
- Analysis of innovations in patient immobilization and radiation delivery systems.
- Focus on advancements facilitating frame-less SRS.
Main Results:
- Significant progress has been made in developing non-invasive methods for patient head immobilization.
- Innovations in imaging and treatment planning enhance the accuracy of SRS delivery.
- New technologies are expanding the applicability and safety of SRS.
Conclusions:
- Technological advancements are making stereotactic radiosurgery more accessible and less invasive.
- The shift towards frame-less SRS represents a major innovation in neuro-oncology.
- Continued innovation promises further improvements in treating intracranial targets with SRS.
