Humanity received many benefits from the emergence of X-ray imaging and its use in the diagnosis of different pathologies, so researchers were encouraged to introduce other energies and other less aggressive methods in their eagerness to explore the most remote and hidden corners of the body, replacing the dangerous ionizing radiation with ultrasound, radioactive isotopes, thermography, infrared rays and nuclear magnetic [...] development of health technologies is necessary, which includes not only equipment, instruments and therapeutic procedures, but also the knowledge, skills and values of health professionals. Within health technologies, we find the term Bone Densitometry, known as the test of excellence for the study of bone density, which includes all non-invasive diagnostic tests that measure the Bone Mass in different parts of the body by means of ionizing or non-ionizing techniques.
