ABSTRACT

Electromagnetic and electromechanical systems are less expensive, easily transported, and allow immediate visualization of the anatomical points of clinical interest [3]. The main limitations of these systems are: the need for absolute patient immobility during digitization of the landmarks (that is very difficult to achieve due to long delays during points collection), and the fact that contact between the measuring instrument and the skin can deform the tissue, thus yielding imprecise models [5].
