Three-Dimensional Reconstruction of Foot Based on Marching Cubes

Abstract

Three-dimensional medical image reconstruction for both transmission and emission tomography has traditionally decomposed the problem into a set of two-dimensional reconstructions on parallel transverse sections. An approach for reconstructing tomographic images based on the idea of continuous dynamical methods is presented. The method consists of a continuous-time image reconstruction (CIR) system described by differential equations for solving linear inverse problems.In this paper, it is provided to reconstruct three-dimensional(3D) models of human body by using CT slices and digital images and precisely finding locations of pathological formations such as tumour. It is necessary to incise a 3D object to obtain detail structure information inside in the process of developing 3D medical visualization system. We design the program reconstruct 3D images utilizing the CT slice sequence in PAT format based on marching cubes by visual C++ 6.0 and Visualization Toolkit (VTK) toolbox,which are used to Cuboids that can be controlled to zoom, move or circumrotate by mouse and used for clipping the object of 3D object. The results supplied by the proposed algorithm are examined with the help of some relevant examples.
