Radiotherapy treatment planning is a process to find the radiotherapy device parameters that give a high dose to the tumour while sparing the surrounding healthy tissues as much as possible. The radiotherapy treatment planning workflow consists of several complex steps, such as contouring of organs-at-risk/target on CT scans and treatment plan optimisation. Some of these steps require manual interventions that cause the treatment planning process to be time-consuming and subject to inter-observer variability [1–6].
