LAB-045: X-ray CT Scans of a Gar Fish Specimen

X-ray CT scans of a Lepisosteus osseus (gar fish) specimen collected in Louisiana on 22 March 2000. The dataset contains 513 slices with a voxel size of 0.0769mm in X and Y and 0.259mm in Z, scanned by The University of Texas High-Resolution X-ray CT Facility (UTCT) on 1 December 2000. Warp corrections were applied in April 2001.

Use Cases

• 3D anatomical modeling and reconstruction based on the 513 CT slices.
• Comparative morphological analysis of gar fish skeletal structure based on high-resolution scans.
• Algorithm development for image registration or warp correction based on the described manual flipping and correction process.
• Educational visualization of vertebrate anatomy using the detailed, warped-corrected scan data.

Strengths

• High-resolution voxel size of 0.0769mm in X and Y dimensions.
• Specific provenance details including collection date, location, scanner, and correction date.
• Contains 513 slices, providing substantial depth for 3D analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for machine learning.
• The specimen was scanned in two parts and manually flipped, which may introduce artifacts or require special handling for full-body analysis.
