  1. January 26: Training cases will be made publicly available to all interested participants. This consists of 60 subjects, half of which taken from the Prostate-Diagnosis collection (1.5T) and the other half from the Prostate-3T collection (3T). Reference Standard (or Ground Truth) data for each subject are provided in the form of NRRD image segmentations created by expert observers.
  2. March 7: Leader Board cases will be made available a month ahead of the NCI-ISBI Challenge. Participants in the contest will be able to submit their segmentation results for evaluation using this data set. This will consist of 10 cases from the Prostate-Diagnosis collection (1.5T) and the Prostate-3T collection (3T). NRRD segmentations used for generating participant scores will be held by the contest organizers.
  3. April 7: The 2013 NCI-ISBI Challenge will be held at the ISBI annual meeting in San Francisco, CA. Testing data will be made available to participants at this time, which will again consist of 10 cases from the Prostate-Diagnosis collection (1.5T) and the Prostate-3T collection (3T).

Corrections/Updates:

  • 3/22/13 - A competitor reported an issue with case ProstateDx-01-0055, which has a dimension mismatch.  The segmentation has dimensions 400x400x23 whereas the DICOM image series have dimensions of 400x400x34.  We checked the case and indeed the dimensions seems to not correspond on Z (23 vs 34), however the labels are properly spatially placed. We don't currently see a problem with using the case.  
  • 3/26/13 - A competitor reported an issue with ProstateDx-01-0006 in which the labels for the peripheral zone and central gland were flipped.  This has now been corrected in the training set NRRD zip file available below.
  • 4/2/13 - The testing data set is being made available in advance of the meeting for download so that participants can have it loaded prior to the meeting.  The password to unlock the zip file will be provided at the ISBI meeting.  See the Testing section below for full details.
