What is this research about?
At the department of radiotherapy, a radiation treatment plan is made for every individual patient based on imaging scans. The tumour and organs at risk are delineated to optimise dose to the target and minimise dose to healthy surrounding tissue. However, manual delineation is time-consuming, so we have implemented automated delineation with a deep learning (DL) model since 2018. While DL models have high average accuracy, they can make mistakes on individual patients or structures. Therefore, all DL segmentations must be evaluated by clinicians. This requirement reduces clinician trust, limits usability and limits the adoption of DL models.
Therefore, there is a growing interest in methods to automatically assess the quality of DL segmentation and predict the influence of errors on the treatment plan. This information can then be provided alongside the model output to improve clinical implementation of the DL model. Recent research within the UMCG and other hospitals has developed technical solutions for error detection in DL segmentation, but the next challenge is designing tools that clinicians will actually want to use and that present this information in an intuitive way. This requires understanding their workflows, preferences and pain points with DL segmentation.
Therefore, we are looking for a master’s thesis student who wants to contribute to developing a clinician-centred auto-QA tool that can be integrated into the radiotherapy workflow to increase the adoption of DL models.
