Radiotherapy and Oncology

Contour delineation is an integral part of radiation treatment planning in the modern era. Both intra- and inter-observer variation are common [1–7], with some evidence suggesting that specialization or expertise could influence contour quality [8] and subsequent patient outcomes [9]. With increasingly complex treatments, contouring has also become a time-consuming process that can limit clinic workflow efficiency [10]. Previous work by our group suggests that radiation oncologists in the United States spend a median of 6 hours per week contouring, despite frequent assistance from dosimetrists and trainees (data in submission), which is comparable to the 5 hours per week reported in a similar survey among radiation oncologists in New Zealand and Australia [11].
