Summary
Stereotactic spine radiosurgery (SSRS) using a conventional linear accelerator offers precise tumor targeting for spinal metastases. This study details an approach using kilovolt on-board imaging for accurate image guidance during treatment.
Area of Science:
- Oncology
- Radiation Oncology
- Medical Physics
Background:
- Stereotactic radiosurgery (SRS) for spinal metastasis involves high radiation doses in 1-5 fractions.
- Precise tumor localization and dose delivery are critical due to the high radiation doses.
- Existing SRS spine studies often utilize the CyberKnife System.
Purpose of the Study:
- To detail an approach for stereotactic spine radiosurgery (SSRS) using a conventional linear accelerator.
- To highlight the use of kilovolt on-board imaging (kV-OBI) and cone beam computed tomography (CBCT) for image guidance.
- To present comprehensive experience with the SSRS procedure.
Main Methods:
- Utilized a Varian Trilogy linear accelerator for SSRS.
- Employed kV-OBI and CBCT for image guidance.
- Detailed patient simulation, immobilization, intensity-modulated radiation treatment (IMRT) planning, beam selection, and portal dosimetry for quality assurance (QA).
Main Results:
- Demonstrated a feasible SSRS approach using a conventional linear accelerator with advanced imaging.
- Detailed the integration of kV-OBI and CBCT for precise tumor localization.
- Presented a comprehensive workflow for SSRS, including planning and QA.
Conclusions:
- Stereotactic spine radiosurgery is achievable with conventional linear accelerators and advanced image guidance.
- The described methodology ensures precise tumor targeting and dose delivery for spinal metastases.
- This approach provides a valuable alternative for SSRS procedures.
