The computed laminography (CL) and limited angle CT (LACT) data sets for the lego sample of the paper are provided, including both raw projection data and the final reconstructions, a total of 4 files for each of the CL and LACT cases. The files are (for CL)

CLProjectionData.zip: zip file with the raw projection images and meta data as produced by the Nikon instrument.

CLShadingCorrection.zip: zip file containing dark and flat field images.

CLreconstruction.mat: MATLAB mat-file with final CL reconstruction, size 798x798x200 voxels.

CLreconstruction.vol: Same CL reconstruction but in a generic binary file that for example simplify the loading of data into Avizo.

The same set of files is available for the CT data. The CT data reconstruction has size 798x798x798.

Accompanying MATLAB reconstruction code is available from
