23 Jul A bone tumor bionic repair system
Abstract
The invention discloses a bionic repair system for bone tumors and belongs to the field of computer-aided biomedical engineering and the system comprises a bone tumor image data input unit, a bone tissue region segmentation and surface morphology reconstruction unit, a bone tumor curved surface model unit, an integrated restoration prosthesis design unit and a bionic multi-cavity integrated restoration prosthesis output unit. Wherein the bone tissue region segmentation and surface morphology reconstruction unit comprises a supervoxel division subunit, a statistical machine learning segmentation subunit and a bone curved surface model reconstruction subunit; The integrated restoration prosthesis design unit comprises a bone loss form restoration subunit, an internal structure design subunitand an internal fixation prosthesis design subunit; According to the personalized and precise bone tumor repair system constructed by the invention, the automation of the design process is improved,and the complexity and inconvenience of the design process are reduced, so that the final repair prosthesis has good biocompatibility and mechanical property.
