Radiation therapy (RT) is indicated for 77% of lung cancer patients. A common adverse event, affecting at least 20% of patients, is radiation-induced lung injury. To minimise radiation-induced lung injury, Professor Keall’s team has invented and pioneered ventilation imaging based on computed tomography (CT) which has been developed into a medical device (CIA). This medical device uses CT scans routinely acquired for planning RT to compute a CT ventilation map showing high functioning and low functioning lung regions.
VitAL aims to investigate whether the use of CIA can be used to direct radiation away from the healthy, high functioning regions towards the low functioning regions, thereby reducing toxicity and improving the patient’s quality of life.
