It also includes the field of telemedicine, which is the more limited area of dealing with the curative part of health care. It includes any situation in which telecommunication is used in the medical field and can be as simple as a patient being able to look up test results via the internet, having a doctor’s appointment by way of a video call or a more complex situation such as one surgeon assisting another during an actual procedure by web cam. The possibilities are endless.
