Obtaining medical images for diagnosis and decision making in the medical field has allowed a great advance in the various areas of emphasis of the health sciences, opening new spaces in which Engineering has provided some of its tools to complement the work and to achieve developments that will allow to delve into fields that could not previously be addressed. With the use of specialized software and from medical images in DICOM (Digital Imaging and Communications in Medicine) format, more precisely the use of Computerized Tomographies, a methodology is proposed for the generation of complex geometries that occur in the human body, which can later be used in different types of studies, among which is the simulation by Finite Elements.
