Based on definitions of tissue engineering scaffold with defect bone, the constructing method for its exterior features was presented. First the pixels of picture at defect area were filled up and then the Boolean operations of filled pixels and original bone pixels were executed, and finally, all the area of filled pixels was 3D reconstructed to obtain the exterior features of scaffold. The 3D-reconstruction idea of the exterior features of scaffold and related projection and Boolean processes of model data for defect area were also analyzed. |
