Lung computed tomography (CT) images are being used to help diagnosis and monitoring of COVID-19 disease. In order to facilitate this task, automated methods for detecting COVID-19 lesions are being developed. These methods are mostly based on deep learning techniques and are already reaching high classification accuracy. However, most of the existing works are restricted to classifying individual cross-sections of the lung CT scan. It is not clear how it should be extended for evaluating the disease on the CT scan volume as a whole and how it should be deployed for practical use. This project will focus on these issues and also investigate aspects such as robustness with respect to data coming from distinct sources. Additionally, if possible, clinical data will also be incorporated in the method to be developed. (AU)
