Patella from CT scan
The patella is the largest sesamoid bone in the body. This anatomically accurate patella, showing the articular surfaces, was extracted from a CT DICOM dataset with 0.3 mm slice thickness. Being an orphaned bone the patella is quite easy to segment from the surrounding soft tissue using CT number thresholding.
The file is in STL format and compressed with ZIP.
Thank you to Dr Mike for the excellent renders.

Feet from CT scan
Bony anatomy and skin surface of the L and R feet, as extracted from a CT DICOM dataset (0.5 mm slice thickness x 250 slices).
This example highlights the inherent difficulty in using CT number segmentation to extract bony anatomy - there are some significant holes present in the structure. When the CT number threshold window was expanded to close these holes, part of the soft tissue was included in the segmentation, corrupting the bony structure. Sometimes even bony segmentation it is not as straightforward as we would like (especially for one of the most complex bony structures in the human body - the feet)!
The skin surface was very easy to extract - just dial up the window width to include all of the dataset. Meshlab was used to clean up the STL, split the file into two separate feet, and reduce the vertex count.
Thanks once again to Dr Mike for the excellent renders and the
