Respiratory gating improves radiation accuracy by timing treatment with your natural breathing cycle—helping protect healthy tissue and reduce side effects.
Respiratory gating is an advanced radiation therapy technique that synchronizes treatment with a patient’s breathing. Tumors located in areas like the lungs, chest, or upper abdomen often shift slightly with each breath. Respiratory gating uses real-time imaging and software to track this motion and deliver radiation only when the tumor is in the ideal position.
During treatment, the system monitors your breathing pattern and defines a precise “treatment window.” Radiation is delivered only when the tumor enters that window and paused when it moves out of range. This ensures that each dose is focused exactly where it needs to be—even as your body moves naturally.
For some patients, especially those undergoing treatment for left-sided breast cancer, a technique called Deep Inspiration Breath Hold (DIBH) may be used. In this method, the patient takes a deep breath and holds it for around 20 seconds. This expands the lungs and shifts the heart away from the treatment field, helping protect it from unnecessary radiation exposure.
At Salter Radiation Oncology, we combine the latest in treatment technology with personalized care tailored to each patient’s needs. Respiratory gating is just one of many advanced techniques we offer to ensure your treatment is not only effective but also as safe and comfortable as possible. Dr. Susan Salter and her expert team work closely with each patient to develop a treatment plan that reflects both the complexity of the diagnosis and the unique needs of the individual.
