Abstract

Radiotherapy is a type of cancer treatment that uses high energy radiation to shrink tumors by destroying cancer cells. It is estimated that 52 per cent of cancer patients can potentially benefit from this type of treatment (Delaney et al. 2005). Planning radiotherapy treatment is a complicated multi-disciplinary process (Aselmaa et al. 2013b). One of the most critical and cognitively challenging steps in the workflow for planning treatment is contouring. Through a complicated underlying cognitive process of ‘sensemaking’, physicians draw the visible boundary of the tumor (i.e. gross tumor volume, GTV) and surrounding organs that are also at risk, as identified in medical images, based on the synthesis of different types of data as well as their knowledge and experience.
