Resumen
Currently, invasive studies are performed on bone parts of corpses or otherwise studies are performed with the geometries and general mechanical properties, this procedure by its application has disadvantages compared to any other that does not require physical intervention of the subject, so in this text we intend to develop a non-invasive methodology, based on computed tomography (CT), which will allow the recreation of a bone model (bone) in a 3D environment, by converting DICOM files to. STL format, which is a type of file used in additive engineering for the printing of 3D models. As a remarkable measure for this project, the main cortical and trabecular parts of the modeled bone will be defined by selecting the thresholds defined by the software for the reading of these DICOM files, that according to the tonality of the image can perform the detection of various tissue densities such as the cortical and trabecular part of the bone, followed by a meshing that allows us to solve a FEA study with ANSYS software in an optimal way for the hardware to be used. Likewise, the independent assignment of specific material properties for each type of bone, in order to obtain information on the behavior of the cortical and trabecular bone as a whole when applying defined restrictions and loads; thus recreating the normal condition of the bone as accurately as possible, it is intended that this method can be applied to the prevention of bone fractures, the design of prostheses and the development of new accessible practices that have a place in this field of study.
