A major goal is to support long-distance health care for patients who are unable to easily travel to the point of care. Patients and professionals are also able to obtain further knowledge on health topics. As a part of the U.S. Department of Health and Human Services, the Office for the Advancement of Telehealth (OAT) promotes the use of telehealth technologies.[8] Sharing medical images over long distances can happen instantaneously with these technologies, allowing a physician to review a patient's images during the conference.
