Stereotactically guided convergent beam irradiation with a linear accelerator: localization-technique.

Area of Science:

• Neurosurgery
• Radiation Oncology
• Medical Physics

Background:

• Stereotactic radiosurgery (SRS) enables precise, high-dose radiation delivery to intracranial targets.
• Accurate patient and target localization are critical for SRS efficacy and safety.
• Existing localization methods may have limitations in precision for SRS.

Purpose of the Study:

• To describe a novel stereotactic convergent beam irradiation technique for radiosurgery.
• To introduce a developed stereotactic localization system designed for precise SRS targeting.
• To enable the precise delivery of single high radiation doses (≥50 gray) to brain lesions.

Main Methods:

• Development of a stereotactic convergent beam irradiation technique utilizing a linear accelerator.
• Implementation of a specialized stereotactic localization system for accurate patient and target point identification.
• Application of the technique for delivering high single doses of radiation to brain targets.

Main Results:

• The developed technique allows for precise application of high radiation doses (up to and exceeding 50 gray) to brain lesions.
• The stereotactic localization system ensures accurate positioning of the patient and the irradiation target.
• Successful implementation of radiosurgery using the described convergent beam technique.

Conclusions:

• The described stereotactic convergent beam irradiation technique is effective for precise radiosurgery.
• The developed stereotactic localization system is essential for achieving the required accuracy in SRS.
• This approach facilitates the safe and effective treatment of brain lesions with high-dose radiation therapy.
