Participants who have registered their team and signed the confidentiality agreement are eligible to download the data. The data consists of two parts:

  1. Training images for 32 patients, with a corresponding reference standard.
  2. Test images for 40 patients, without a reference standard.

Images have been acquired on four CT scanners from four different vendors. For each vendor, the data consists of an equal number (8 for training, 10 for testing) of CT examinations. Each examination contains a CT image and a CTA image. The training set contains a labeled image with reference annotations for each CT image. For details about the reference standard, please visit the Data page. Filenames contain the set the image is in, a vendor identifier, a patient identifier and the image type. For example, the filename TRV1P1CTI.mhd stands for:

  • TRaining. Test image filenames start with 'TE' or 'VA'.
  • Vendor 1
  • Patient 1
  • CT Input. CTA image filenames end in 'CTAI', filenames for labeled images with reference annotations on the CT images end in 'R'.

The image files are written in the MetaImage format (mhd+raw file). This format consists of a text file ending in .mhd which contains ASCII header information and a binary file ending in .raw that contains the voxel data. ITK supports this format. For more information see this page.
