X-ray CT Scans of a Pisaster Sea Star Specimen from 2001

The University of Texas High-Resolution X-ray CT Facility provides 92 slice images from a CT scan of a formalin-preserved Pisaster sea star. Scanned on 8 February 2001, the data has a voxel size of 0.119mm in X and Y dimensions and 0.102mm in Z. Image processing was performed by Matthew Colbert and Farrah Welch for Dr. Timothy Rowe.

Use Cases

• 3D model reconstruction of sea star anatomy based on the 92 CT slices.
• Analyzing internal morphological structures based on the specified voxel resolution.
• Developing or testing image segmentation algorithms for biological CT scans.
• Comparative anatomical studies of echinoderms using high-resolution scan data.

Strengths

• Scan parameters are explicitly documented, including voxel sizes (0.119mm X/Y, 0.102mm Z) and total slices (92).
• Provenance is clear, citing the scanning facility, date (8 February 2001), and personnel involved.
• Specimen preservation method (formalin) is noted, which is relevant for image interpretation.

Limitations

• Description metadata is limited; actual data quality, file formats, and size require manual inspection after download.
• Row count is unknown, which may limit suitability assessment for machine learning pipelines.
• Column-level documentation is absent; field semantics and image metadata must be inferred after download.
