Objective Aim to create a three-dimension（3D） reconstruction of acupuncture needling at Sidu（四渎 TE 9）.Methods First,the skin,subcutaneous tissue,muscles,the blood vessels and nerves near TE 9 were defined in anatomical ***,the above anatomical structures including the dissected muscles associated with at TE 9,the underlying blood vessels and nerves were reconstructed in ***,the process of acupuncturing TE 9 on a virtual human body was simulated using the VOXEL-MAN *** Both the local anatomy of the point and the process of acupuncture needling at TE 9 were *** layers of tissues were visualized during the process of needling,as the needle was inserted and manipulated at the *** Virtual 3D reconstruction can contribute to research on the anatomical structure of acupoints and the visualization of the *** recommend that it be fully utilized in acupuncture research.

Diagnostic Value of 16 Slices Spiral-CT for Portal Vein Disorders

Journal of Huazhong University of Science and Technology(Medical Sciences) 2004年第3期24卷 300-302页

Summary: The diagnostic value of 16-slices spiral computed tomography (CT) for portal vein disorders was evaluated. Forty-one patients were scanned by the 16-slices spiral-CT. The celiac trunk, portal vein and their branches were reconstructed by volume rendering (VR), multiplanar volume reconstruction (MPVR) and maximum intensity projection (MIP) technique, and the results were compared with digital subtraction angiography (DSA). VR, MPVR and MIP could display celiac trunk, portal vein, inferior vena cava and their branches and extent of portal vein-vena cava shunt, portal vein emboli and the fistula of hepatic artery-portal vein. The results from 16-slices CT were better than DSA and identical with pathologic ones. The vessel three-dimension reconstruction technique of 16-slices spiral CT is valuable for evaluating the portal systemic disorders.

Objective To establish a three-dimensional model of the temporal bone using CT scan images for study of temporal bone structures and simulation of mastoidectomy procedures. Methods CT scan images from 6 individuals (12 temporal bones) were used to reconstruct the Fallopian canal, internal auditory canal, cochlea, semicircular canals, sigmoid sinus, posterior fossa floor and jugular bulb on a computer platform. Their anatomical relations within the temporal bone were restored in the computed model. The same model was used to simulate mastoidectomy procedures. Results The reconstructed computer model provided accurate and clear three-dimensional images of temporal bone structures. Simulation of mastoidectomy using these images provided procedural experiences closely mimicking the real surgical procedure. Conclusion Computer-aided three dimensional reconstruction of temporal bone structures using CT scan images is a useful tool in surgical simulation and can aid surgical procedure planning.
