Popis: This paper describes reverse engineering (RE) of the human fibula, on the right male bone, by using the method of anatomical features (MAF) with the aim to obtain a 3D surface model. The first step in the process of reverse engineering is CT scanning and digitalization of data. CT data are obtained with the Toshiba MSCT scanner Aquillion 64 and saved in the DICOM format. They are subjected to further processing and imported in the Computer Aided Design (CAD) program as a STL file. The process continues in the CAD program with identification and determination of the Referential Geometrical Entities (RGEs) which are crucial for RE process. The RGEs are the basis for defining the axis and planes of intersection. The intersecting polygonal model of the human fibula, namely upper and lower extremities and the body with these planes, results in a set of curves used for determining points on the given planes. Through these points the splines are pulled, and with loft function surface models of extremities and the body of fibula is built. Joining and merging of these models leads to 3D shape model of fibula. The model accuracy is confirmed by conducting distance and deviation analysis. The model is suitable for rapid prototyping, reconstruction of the missing parts of fibula, orthopedic training and simulation.
