Description

This is the 3D model of the healthy adult hand. More specifically, it is a model of a standard registration template of healthy adult human hand. (During medical image analysis, it is often useful to align, or ‘normalize’, a given image of a given body part to a representative standard, or ‘template’, of that body part. Normalizing images in this fashion ensures that a given voxel of each registered image represents the same anatomical part.) We created the template using T1-weighted MR images of 27 different healthy adult hands from 21 different subjects. The subject sample was fairly representative from a demographic viewpoint (14 and 13 images of left and right hands, respectively; 8 men and 13 women; mean age, 35.9 years±17.9 [standard deviation]; age range, 19.4–66.9 years; African American, 2; Asian 3; Caucasian, 14; Latino, 2). The template was created using the ANTs (Advanced Normalization Tools) software platform. The resulting NIfTI image of the hand was segmented using 3D Slicer (version 4.13.0-2022-04-12), and the hand segment was exported as the above .STL file.
