Summary
Stereotactic body radiation therapy (SBRT) uses image-guided radiation therapy (IGRT) for precise high-dose treatments. This review covers clinical experience with volumetric and ultrasound image guidance for SBRT.
Area of Science:
- Radiation Oncology
- Medical Imaging
Background:
- Stereotactic body radiation therapy (SBRT) is an advanced external beam radiation technique for treating small lesions outside the brain.
- SBRT utilizes stereotactic conditions for high-dose radiation delivery in one or few fractions, emphasizing normal tissue sparing through steep dose gradients.
Purpose of the Study:
- To review clinical experience with volumetric and ultrasound-based image-guidance for SBRT.
- To discuss challenges and limitations associated with pre-treatment image-guidance in SBRT.
Main Methods:
- The review focuses on image-guided radiation therapy (IGRT) techniques, specifically volumetric (e.g., CT) and ultrasound-based methods.
- These advanced methods ensure accurate target volume positioning relative to radiation beam geometry before treatment delivery.
Main Results:
- Clinical experience with volumetric and ultrasound image-guidance for SBRT is summarized.
- The review presents and discusses the challenges and potential limitations inherent in pre-treatment image-guidance for SBRT.
Conclusions:
- Image-guided radiation therapy (IGRT) is crucial for the accurate delivery of stereotactic body radiation therapy (SBRT).
- Volumetric and ultrasound-based IGRT show promise but require careful consideration of their associated challenges and limitations.
