Abstract
Surface-Guided Radiation Therapy (SGRT) is a newly advancing technology in radiation therapy that improves the accuracy and safety of radiation therapy treatments. SGRT utilizes three-dimensional images of the patient’s surface in real-time, which improves patient setup accuracy and allows for continuous patient monitoring, while decreasing the need for additional imaging in comparison to the traditional laser setup method. The project discusses the advantages of SGRT and the utilization of the technology for breast and lung radiation treatments. In breast cancer treatments, SGRT improves positioning accuracy and reproducibility, as well as decreases radiation dose to the heart and lungs while using deep inspiration breath hold (DIBH). In lung cancer treatments, SGRT decreases setup errors, radiation dose to the patient and treatment time, as well as improves reproducibility of respiratory motion. Additional benefits of the utilization of SGRT includes the elimination of the need for permanent skin marks, reduced close contact between patients and radiation therapists, which decreases disease transmission, and easier setup for radiation therapists compared to conventional setup methods. Overall, SGRT demonstrates a highly advancing technology in radiation oncology, which improves treatment efficiency and accuracy. As SGRT continues to evolve, the technology is expected to become more common in the radiation therapy field; however since SGRT is a new technology, further research is needed to assess the long-term effectiveness.
