Imaging is one of the most important technologies developed for the field of medicine. But imaging is only one of a wide variety of medical solutions developed by biomedical engineering.

Biomedical engineers create a wide variety of devices, technological processes, and conduct research using knowledge of life sciences and engineering practices. The benefit to using technology is to solve significant health problems such as the solution of the polio vaccine. Technology in medicine is valuable in that it saves and improves lives, but can be very expensive and drive up healthcare costs. Governments and individuals have to determine what they are willing to pay for. So values of individuals and societies decide the healthcare options available for a given individual.
