Why Surface Guided Radiation Therapy

Radiation Therapy is one of the most common treatments for cancer, in which high-energy radiation is administered to the body to shrink tumors and kill cancer cells. It can be a stand-alone treatment, or is commonly used in combination with chemotherapy, surgery, or hormone therapy. About half of all cancer patients receive some type of radiation therapy during the course of their cancer treatment*.

If you have radiation therapy, it’s important to ensure the radiation reaches the right place throughout the course of treatment, while avoiding vital organs such as the heart. To do this, a variety of techniques are used to ensure the patient remains correctly positioned before and during treatment. These range from obtaining additional X-Ray images of the patient to physically restraining areas of the body throughout the treatment duration, which can be uncomfortable and counter-productive.

Surface Guided Radiation Therapy (SGRT) is a new technique that’s becoming widely used to ensure patients are positioned correctly before and during treatment. By tracking the skin surface using Vision RT’s non-ionizing and non-invasive camera technology, SGRT helps make sure the patient is in the intended position, with high accuracy, and often with less physical immobilisation, providing both comfort and safety. If the patient moves, radiation can be automatically paused until they are back in the intended position. SGRT is used across a wide range of cancer types and sites.
