Deutsch Русский About Us Products Applications Case Studies Education For Patients Get In Touch Introduction to Surface Guided Radiation Therapy (SGRT) Surface Guided Radiation Therapy (SGRT) is a rapidly growing technique which uses stereo vision technology to track patients’ surface in 3D, for both setup and motion management during radiotherapy. SGRT can be used for many types of radiation therapy. There are numerous publications that support its use in the treatment of breast, brain, head and neck cancer, sarcoma, and other conditions. Example Applications of SGRT with AlignRT Radiation therapy has been shown to be a highly effective treatment for breast cancer, but the proximity of the left breast to the heart leaves the heart vulnerable to radiation exposure. This has been shown to lead to serious long-term cardiac complications. In one study of patients treated for left breast cancer, 27% exhibited cardiac perfusion defects within six months 1 . Many centers are beginning to have patients use a Deep Inspiration Breath Hold (DIBH) to move the heart away from the breast during therapy. However, achieving this can be challenging 2 . Patients breathe in different ways at different times, and may arch their back to simulate a deep breath in. These different movements can appear similar to a patient’s true breath hold, but do not necessarily separate the heart from the breast. A recent study 3 showed that AlignRT + DIBH effectively prevented radiation-induced abnormalities in blood flow to the heart. Of the breast cancer patients treated, 0% showed these abnormalities after six months. This compares to a previous study without AlignRT or DIBH, where 27% of patients showed new abnormalities in blood flow to the heart 6 months after radiation therapy 4 . Additionally, there are more than 10 publications that demonstrate the accuracy of the technique. Get in touch to learn more about AlignRT SGRT technology.
