Imaging will continue to expand beyond its current mainly diagnostic boundaries into therapy. Imaging will replace direct visions in ranging fro minimally invasive devices to the most complex robotic instruments. Whether it is using radio-frequency, lasers, endoscopes, or gene therapy, imaging will become increasingly integrated to the physical manipulation of the body.

Imaging will also encroach on the time-honored physical examination in the primary initial assessment of patients, although it will never replace the need for touch and understanding. Imaging will move far beyond its current structural foundation to encompass physiology. Imaging will move far beyond its current structural foundation to encompass physiology, and ultimately molecular function. As imaging undergoes this metamorphosis it will have broadening applications not only in the assessment of disease, but in screening for pre-disease states, which will be commonplace in the new era of genetic medicine. In a consumer-driven health care environment, imaging of the body will be key to patients in defining and managing their health status.
