Material: transparent solid material with muscles
Data source: digital model of the human body
The 3D-printed model of the blood vessels and nerves of the hand is a transparent wrapping model. The skin, superficial fascia, deep fascia, and other structures are made of transparent material, while the bones, ligaments, blood vessels, nerves, and muscles are made of full-color material. The internal anatomy is clearly visible through the transparent materials. The internal anatomical structure corresponds to a real specimen, and the transparent wrapping material preserves the spatial arrangement of anatomical structures, accurately conveying the morphological features of normal blood vessels, nerves, and muscles of the hand.
Data source
The data were extracted from high-precision digital anatomical images, including original tomographic data, refined segmentation, and 3D geometric models of organ structures such as bones, muscles, blood vessels, nerves, ligaments, and other anatomical structures. The voxel size in this dataset example is 0.0384 mm * 0.0384 mm * 0.1 mm. Also, formalin-fixed body specimens were selected as a basis for 3D printing for comparison and validation of the model.
Modeling: the surface voxels of each anatomical structure were extracted from the original tomographic dataset to create texture maps of the geometric model, ensuring that the appearance of the geometric model of each anatomical structure has the same visual look as the actual anatomical specimen.
