Conclusion:

A combined end-to-end framework was utilised in this study to classify RT structures. Our experiments demonstrate that the use of multi-modal data can improve the performance compared to univariate models. The developed model has the potential to be utilised to retrospectively classify inconsistent structure names into standardised nomenclature, adhering to national and international consensus guidelines. Such automated systems will have potential to address inconsistencies among RT structure names in a platform that utilises multiple large-sized clinical practice databases and for real-time quality assurance use, reducing the risk of mislabelled data. We therefore propose the development of this work using breast cancer data as a pilot that could be successfully extended for other tumour sites in the future.
