Lego Sample X-Ray Laminography and CT Data with Reconstructions

4 files each for computed laminography and limited-angle CT data of a lego sample, including raw projections and reconstructions. The CL reconstruction is 798x798x200 voxels, and the CT reconstruction is 798x798x798 voxels. This data accompanies a 2019 Measurement Science and Technology publication by researchers including Sarah L Fisher from the University of Manchester.

Use Cases

• Benchmarking computed laminography reconstruction algorithms based on the provided raw projection data.
• Comparing limited-angle CT and laminography techniques using the paired datasets of the same lego sample.
• Developing shading correction methods for X-ray imaging using the provided dark and flat field images.
• Testing 3D visualization software with the provided reconstruction files in .mat and .vol formats.

Strengths

• Includes both raw projection data and final reconstructions for two imaging techniques.
• Reconstruction voxel dimensions are explicitly stated (798x798x200 for CL, 798x798x798 for CT).
• Accompanied by open-source MATLAB reconstruction code from a GitHub repository.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect methodological bias inherent to the specific experimental setup described in the paper.
