An Overview of the Development of Stereotactic Body Radiation Therapy
This is an incremental overview for clinicians and researchers in radiation oncology, summarizing existing knowledge without introducing new findings.
The paper discusses the development of stereotactic body radiation therapy (SBRT), a radiotherapy method that focuses high-energy rays on tumors to improve local control rates and reduce complications, based on advancements in medical imaging and radiation biology.
Stereotactic body radiation therapy (SBRT) refers to focusing high-energy rays in three-dimensional space on the tumor lesion area, reducing the dose received by surrounding normal tissues, which can effectively improve the local control rate of the tumor and reduce the probability of complications. With the comprehensive development of medical imaging, radiation biology and other disciplines, this less-fractional, high-dose radiotherapy method has been increasingly developed and applied in clinical practice. The background, radio-biological basis, key technologies and main equipment of SBRT are discussed, and its future development direction is prospected.
