| Summary: | 碩士 === 國立臺北科技大學 === 工業工程與管理系碩士班 === 105 === Skull defects can lead to risk of brain infection, low brain protection situation, and mental social barriers. In order to avoid these situations, we must build a prosthesis and transplant it to the defect area. With the development of Additive Manufacturing and 3D printing technology, skull prosthesis can be manufactured precisely and efficiently during skull reconstruct surgery. However, the skull prostheses made by the metal implants are not always in full compliance with the needs of the defective area. Unsuitable prosthesis may cause repeated brain infections and require secondary surgery. This study proposes a Differential Evolution Algorithm and an Active Contour Models to construct suitable skull prosthesis. It can be adjusted in each tomography slice according to the graphic features. The proposed method can model the defective region of the skull defect, and the resulting pattern can fully simulate and compensate for the skull defect area. So that clinical surgeons can implant the prosthesis very quickly into patient, especially in emergency surgery. This study can solve the problem of skull defects, so that patients can get the best help in surgery.
