Lake Sturgeon Head CT Scans with 0.026 mm Voxel Resolution

468 X-ray CT slices of an Acipenser fulvescens (Lake Sturgeon) head specimen collected in Michigan in September 1991. The data was scanned on 20 May 2003 by The University of Texas High-Resolution X-ray CT Facility (UTCT) for researchers at The University of Texas at Austin. Voxel sizes are 0.02636 mm in X and Y dimensions and 0.0986 mm in the Z dimension.

Use Cases

• 3D anatomical modeling and segmentation based on the high-resolution CT slices.
• Comparative morphological analysis of sturgeon cranial structures.
• Algorithm development for processing volumetric biological imaging data.
• Educational visualization of fish skeletal anatomy.

Strengths

• High-resolution scanning with precise voxel sizes documented (X/Y: 0.02636 mm, Z: 0.0986 mm).
• Total slice count is explicitly stated (468 slices).
• Provenance is clearly documented, including specimen origin, collection date, scanner, and date of scan.

Limitations

• Description metadata is limited; actual data quality, file formats, and size require manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data represents a single specimen from a specific location and time, which may limit generalizability.
