Welcome

The Contouring Challenge is a multi-centre research initiative hosted by the Turku PET Centre, addressing the accuracy and variability of standard and emerging contouring methods for oncological volume-of-interest segmentation in PET and PET/CT images for radiotherapy treatment planning.

Anonymous diagnostic and phantom images were released to participating teams for contouring at the end of October 2010, and contouring results were returned for analysis at the end of February 2011.

Experiments were designed to demonstrate new ways of evaluating contouring performance in the absence of absolute 'ground truth', and to compare the quality of different contouring methods.

Results were presented at session 2 of the software sessions at the XII Turku PET Symposium (28.05 - 02.06) and posted on-line to coincide with the symposium.

The links on the left describe how the challenge proceeded and give details of the experimental methods and results.

We wish to thank all teams for taking part and welcome all feedback addressed to
