Artificial Intelligence for Medical Image Analysis


This strand of our AI work aims to predict the future state of the patient. This can involve risk prediction as well as prediction of response to treatment as well as toxicity arising from treatment.

Predicting response to cardiac resynchronisation therapy

Cardiac resynchronisation therapy (CRT) is a treatment for heart failure which involves implanting a pacemaker into the heart to restore electrical and mechanical synchrony. This procedure is invasive and not without risk, but approximately 30-50% of patients do not respond positively to the treatment. Therefore, there is interest in predicting which patients are likely to respond using pre-treatment imaging data. Over the years we have proposed a number of frameworks to address this problem, starting with classical machine learning approaches and progressing to the latest deep learning methods. Along the way, we have addressed the issues of interpretability and trust in the models with a view to developing an AI model for CRT response prediction which could act as a decision support tool for cardiologists.​

Predicting toxicity in radiotherapy

Radiotherapy dose map overlaid onto CT scan of mandible area.

Mandible osteoradionecrosis (ORN) is one of the most severe toxicities in patients with head and neck cancer undergoing radiotherapy. Previous literature has focused on examining correlations between mandible ORN and clinical and dosimetric factors. In this work, for the first time we investigated the use of machine learning methods to make personalised predictions of mandible ORN incidence.
