Imagine that the doctor or the medical team can check the patient's condition, get his laboratory results and make the necessary prescription as quickly as possible without visiting the office. All these are examples of the new technology that we use. We know it as telemedicine. The word telemedicine is composed of two words, tele, which is a Greek word meaning "long-distance communication" and the word medicine, which means treatment and medicine.

From the point of view of information technology, telemedicine means the provision of medical services from a long distance and through networks that support the transmission of voice, video and computer data.

For the implementation and application of telemedicine on a wide scale, the following tools can be used:

Internet network for education and access to medical information and advice.

virtual reality using simulators; In this way, with the help of simulators, people acquire the necessary skills and training in an experimental manner to face real situations and unexpected events; Such as: simulating medical emergencies on battlefields or during earthquakes, floods, and fires.

Using video conferencing and conducting video consultations.

The use of pocket computers and PDAs, by rescuers, doctors and other people, to send the necessary information and get immediate advice from anywhere in the world.

Using smart clothes to send the person's condition to the medical team; Such as sending the status and geographic location of soldiers and war wounded to rescuers

Objectives of telemedicine and electronic health:

     Improving patient care

     Improving access and medical care for rural and deprived areas

     Better access to doctors for consultation

     Providing facilities for doctors to direct automatic examinations

     Reducing the cost of medical care

     Creating medical care services (on a wide geographical and population level)

     Reducing the transfer of patients to medical centers

     Creating a managed care environment in hospitals and medical centers

     On the ship, in the plane

     war zones

     Distant prisons

Problems and obstacles:

     Increase the possibility of misdiagnosis

     Hardware cost

     The need for a good communication network

     Staff training: One solution is to include telehealth training in the curriculum of medical schools.

     Educating patients and users: because many people do not know about TeleHealth and its capabilities and limitations, so the benefits of this system should be taught to them.
