Abstract

Intensity modulated radiotherapy is a widely used technique for accurately targeting cancerous tumours in difficult locations. As treatments are becoming more complex, new methods need to be developed to monitor them. Monolithic active pixel sensors are a viable candidate for providing upstream beam...
