Telemedicine may have been in prominence in the past four
years, but in reality telemedicine has been in
use in some form or other for over thirty years. The
National Aeronautics and Space Administration (NASA)
played an important role in the early development of
telemedicine. Many of the initial telemedicine endeavors involved transfer of images over microwave
and audio frequency ranges. Astronauts in space were
monitored from the spacecraft as well as their spacesuits
during their missions. |
Telemedicine is now becoming useful in a many spheres of
medicine viz. Dermatology, Oncology, Radiology, Surgery,
Cardiology, Psychiatry, Gynaecology, Paediatrics and Home
Health Services for remote areas where no such specialist is
available.
