Telemedicine, which is a rapidly growing practice, refers to the use of the internet or phone by doctors and patients to communicate with specialists, other physicians, and patients. Sometimes, a doctor can even conduct examinations and procedures over any of the media today.

Although procedural medication using telecommunication technology is a relatively new technology, it was used in its early form by African Villagers as smoke signals. These signals were used to warn others not to go to their villages in order to prevent them from contracting a contagious disease.

Telemedicine uses a "tele" prefix. Then following is the practice specialty, such as teleradiology and telepsychiatry. 

Telecardiology, tele neurology, and even teledentistry are just a few of the other specialties that fall under this prefix. As you can see, technology is being used in almost all areas of medicine.

You might have even noticed that x-rays were sent over the internet to your referring doctor. Instead of a large yellow envelope with film, you received a small disc that you could easily carry around in your pocket or purse.

Telemedicine was initially considered most useful for remote villages and towns. It has since been used in almost all medical facilities.

Telemedicine technology can be cost-effective and even lifesaving for patients who cannot travel to major medical centers.

Telemedicine technology has many benefits for healthcare. Geriatric patients who are homebound or in a convalescent facility may benefit from telemedicine technology. It is possible that they are unable to or unsafe to travel to an office. 

These cases can be handled by video conferencing software, which allows the doctor to see and hear both the patient and the on-site medical professional.
