3D Reconstruction of CT Images Based on Isosurface Construction

With development of modern medical imaging computer technology, the rapid prototyping manufacturing and 3D visualized medical accessory system reality were achieved based on CT. Aiming at the key technology of 3D reconstruction from medical CT images, a 3D medical imaging surface reconstruction scheme was proposed, which integrated segmentation with marching cubes (MC) algorithm. Firstly, the shortage of standard MC algorithm was analyzed that caused huge consumption of operation and was hard to work out ,then it indicated the special MC(SMC) algorithm to make 3D reconstruction from medical spiral CT images. Finally, the experiment of two algorithms was accomplished with Visual C++. The experimental data of tooth showed that the SMC could reduce unnecessary cube on the calculation and simplify the reconstruction methods.
