摘要
To find out the advantages and insufficiency of the 3D reconstruction and traditional anatomy by comparing them with each other. 1. Infused with the radio-opaque material from the arteries and veins, respectively, fresh lower extremity specimens were subjected to spiral CT scanning and then 3D reconstruction was conducted to obtain 3D vessels. 2. Anatomizing the specimens to show the vessel system. 3. Comparing the images of 3D reconstruction and photos of the dissected specimens. 3D software could dissect and reconstruct the bones, vessels, skin and muscles, and the reconstructed photos could be shown, respectively or combinedly. On the other hand, the course, distribution, and anastomoses of the vessels could be viewed from different aspects and different layers, but the results were not completely correct, so they were not suitable for data acquisition. While the vessel systems could be observed clearly on the dissected specimens, so could the origin, course, distribution and the anastomoses of any vessel. The data acquisition could be conducted. The method of angiography with 3D reconstruction is very good and has considerable advantages for observing the 3D state of human blood vessels, and their distribution at different angles and different levels, but it cannot totally represent or replace the traditional dissected specimens.
