Welcome to the Circle of Willis (CoW) Benchmark joint-event for MICCAI 2023!

We are two CoW benchmarking challenges with MICCAI 2023:

  • ๐Ÿ‘‘ CROWN: CiRcle Of Willis INtracranial Artery Classification and Quantification
  • ๐Ÿฎ TopCoW: Topology-Aware Anatomical Segmentation of the Circle of Willis for CTA and MRA

Together both challenges will organize a joint event called the โ€œCircle of Willis Benchmarking Workshopโ€ at the MICCAI Conference. In this half-day joint-event, we are excited to present three clinical keynotes ๐Ÿฅ ๐Ÿง  on the topic of CoW, followed by two 1.5 hours sessions to summarize and announce the results for each challenge. We will host a combined round-table discussion with all participants.
