This data set was provided in association with a challenge competition and related conference session conducted at the AAPM 2017 Annual Meeting . The initial winners were announced at the AAPM meeting, but the competition website remains open to others who wish to see how their algorithms perform.
Numerous auto-segmentation methods exist for Organs at Risk in radiotherapy. The overall objective of this auto-segmentation grand challenge is to provide a platform for comparison of various auto-segmentation algorithms when they are used to delineate organs at risk (OARs) from CT images for thoracic patients in radiation treatment planning. The results will provide an indication of the performances achieved by various auto-segmentation algorithms and can be used to guide the selection of these algorithms for clinic use if desirable.
