ABSTRACT
Introduction: Current DICOM viewers and their ability to generate three-dimensional reconstructions generate a high interest in engineering application in the analysis by the Finite Element Method (FEM) and in mechanical simulations of real bone. The ability to quantify the mechanical properties from medical imaging is useful in the fields of implant design as so as surgical navigation and planning.
Material and Methods: To achieve this objective it is necessary to infer the mechanical properties of tissues in terms of the generated medical image. Different methods are evaluated on the basis of their advantages and disadvantages and the results produced by each of them. Finally, a bone structure is isolated in terms of its mechanical properties, showing areas with better structural quality, and those with better capacity for bone regeneration.
Results: Several methods have ranges of divergence with a magnitude that makes them unreliable for use in engineering, the divergence was evident in terms of image acquisition system, patient and diagnosis protocol used.
Conclusions: The most reliable method, within the wide discrepancies observed, requires the use of patterns in the process of image acquisition to facilitate the determination of mechanical properties related to pattern values.
KEY WORDS: medical imaging, three-dimensional reconstruction, bulk density, finite element method, bone tissue, mechanical properties.
