ABSTRACT
<p><b>OBJECTIVE</b>To discuss the problem difficult to be presented for nerves and blood vessels in the 3D reconstruction of acupoints through studying 3D reconstruction of Jianliao (TE 14).</p><p><b>METHODS</b>Muscles and other tissues were segmented by applying cointeractive segmentation method based on chromatic characteristic space; the nerve and blood vessels can be reconstructed by establishing mathematics model, and the needle-inserting animation of Jianliao (TE 14) could be obtained by running script file.</p><p><b>RESULTS</b>During the course of 3D needle-inserting animation of Jianliao (TE 14), the spatial location between all kinds of tissues including the nerve and blood vessels and the needle body could be systematically observed.</p><p><b>CONCLUSION</b>The difficulty of presenting the nerve and blood vessels in the study on 3D reconstruction of acupoints can be resolved by establishing mathematics model. The generation of 3D animation for acupoints with the nerve and blood vessels is benefit to acupuncture teaching and study on the essence of acupoints and channels.</p>
