Validation Dataset for the ICASSP-2024 3D-CBCT challenge https://sites.google.com/view/icassp2024-spgc-3dcbct/home Please dowload all files into one folder, and then merge them together with: $ zip -s 0 validate.zip --out validate_unsplit.zip This will create a new zip file, "validate_unsplit.zip" that then you can unzip with your favourite tool, e.g. $ unzip validate_unsplit.zip The CBCT geometry required to be used image size : [300 300 300] mm image shape : [256 256 256] voxels voxel size : [1.171875 1.171875 1.171875] mm detector shape : [256 256] pixels detector size : [600, 600] mm pixel size : [2.34375, 2.34375] mm distance source origin (axis of rotation, center of image) : 575 mm distance source to detector : 1050 mm Remember that to be part of the challenge you need to register in the webpage above.
