3D Reconstruction of Human Head CT Images Based on VTK

In craniotomy, in order to better help doctors design surgical approaches for patients, it is necessary to conduct three-dimensional reconstruction of patients' heads. This paper introduces two 3D reconstruction algorithms of medical images: Marching Cubes and Ray Casting. The implementation framework of the algorithm is described by visual toolkit VTK. These algorithms were tested on the actual CT data to show different reconstruction effects. According to the experimental results, the quality of CT images used in the experiment will also affect the effect of the reconstruction model.
