Summary

The standard treatment for breast cancer is surgery followed by adjuvant breast radiation therapy in most cases. For left sided breast cancers, the heart dose delivered by the radiation treatment is often of particular concern. In order to spare the heart, different strategies are currently available, including active breathing control (ABC) and voluntary deep in inspiration breath hold (DIBH) (both strategies are currently being used at our centre). To perform accurate heart-sparing treatments, it is important to ensure that patients are positioned consistently. One available approach is through surface imaging which tracks the position of a portion of the skin surface, known as the AlignRT system (VisionRT Ltd, London, UK).
