Micro-CT and CT Scans of Tetrapod Limbs from Dicamptodon and Iguana

A collection of 3D medical imaging data for two tetrapod species, Dicamptodon ensatus and Iguana iguana, stored in DICOM and TIFF formats within a 2.2 GB archive. The dataset was contributed by researcher John Hutchinson and was last updated in April 2026.

Use Cases

• Analyze 3D bone geometry from DICOM and TIFF files to compare limb skeletal structure between amphibian and reptile species.
• Segment and measure specific anatomical features, such as bone density or cortical thickness, from the micro-CT scan slices.
• Use the high-resolution TIFF files for creating 3D mesh models of individual limb bones for biomechanical simulation.
• Train image segmentation models to automatically identify bone boundaries in cross-sectional CT scan data.

Strengths

• Contains high-resolution 3D micro-CT and CT scan data for detailed anatomical study.
• Data is provided in two standard medical imaging formats, DICOM and TIFF, facilitating use with specialized software.
• The 2.2 GB file size indicates a substantial volume of imaging data for the specimens.

Limitations

• The dataset contains scans from only two individual specimens, limiting statistical power for broad comparisons.
• Sample metadata, such as specimen age, sex, or collection details, is not provided in the description.
• The temporal coverage and specific scanning parameters for the images are unknown.
