Data for the prostate challenge has been provided by Boston University and Radboud University, Nijmegen Medical Centre (the Netherlands). The challenge data has been divided into three groups:
A 60 case prostate MRI 3D series "training set" consisting of DICOM images with matched .NRRD markups that defines the tissue "central zone (CZ)" and "peripheral zone (PZ)" are available from the National Cancer Institute (NCI) Cancer Imaging Archive – "TCIA".
There will be 60 cases, each consisting of 15+ (4 mm thick slices at 3T) or 28+ (3 mm thick at 1.5T) adjacent axial cross-section cuts. Half of them were obtained at 1.5 T (Philips Achieva) with an endo-rectal receiver coil (from (BMC) Boston Medical Center) and the other half at 3T (Siemens TIM) with a surface coil (from Radboud University Nijmegen Medical Centre (RUNMC), Netherlands). They were acquired as T2 weighted MR axial pulse sequence. Each file contains nearly all DICOM acquisition parameters except tags that specifically identify Private Health Information (PHI).
To complete the training data set, each case has had individual slice CZ and PZ outlines marked by Drs Nicolas Bloch (at Boston University School of Medicine) / Mirabela Rusu (Case Western U.) or Drs Henkjan Huisman / Geert Litjens / Futterer at RUNMC Netherlands. Use the following links to download the .NRRD markups:
Once you've trained your algorithm on those 60 cases the ISBI Challenge Committee will provide you access to a new 10 case "Leaderboard" set to which you will not have .NRRD markup data. "Leaderboard" is a popular term (borrowed from golf) for a procedure to see how well you are doing on a pre-test set to get a sense your relative competitive rank before submitting to a final test. The results of your participation in the Leaderboard will be returned to you as feedback on a subset of sequestered markups retained on the judging analytic software using Kitware's MIDAS software. You may then use those results for further tuning your algorithm to prepare yourself for the final "Test" set of 10 totally new cases on which you will run your algorithm while attending the ISBI meeting in April 2013.
