Magnetic resonance imaging (MRI) plays an important role in the diagnosis of cancer, as well as in treatment decisions. This form of non-invasive imaging can produce three-dimensional images of the human body that provide useful information to the physician. We can visualize the internal structures of the body and many of its functions, all non-invasively. The outcome of this research program will be new MRI methods for the assessment of cancer, to study the composition and physiology of tumours.

We will develop imaging techniques to inform the planning of radiation therapy treatments, by providing better targeting, sparing organs at risk, and reducing side effects. First, we seek multi-spectral images to accurately identify the treatment target and to gather the required information for radiation dose calculation. Second, we will examine the blood supply to tumours, connected to their potentially malignant behaviour. Once validated, these methods will enable improved treatment planning and a simplified workflow, and will enable us to better measure the response to treatment.
