Application of VTK in three dimensional reconstruction of visible human's head

To better assist surgeons to implement disease diagnosis, operation planning and monitoring in treatment of the brain, the 3D reconstruction of head skin and bones based on CT image sequences provided by visible human project of America using VTK(visualization Toolkit) is realized: 1) By Matlab programming, the medical image in dicom format are read, the skin image and bones image of head are segmented using maximum between-class variance threshold algorithm,and the two segmented thresholds are used as the isosurface extraction values of skin and bone, respectively. 2) The surface rendering of visible human's head is realized by VTK programmed with VC++. The result of experiment shows that this method obtained desired effect of 3D reconstruction, programming quick and simple, and the running time of the program is only 8.4s.
