  • 3. Telehealth
    • Telehealth is using technology to provide medical care over distance
    • non-clinical services such as distance medical education and research
    • It will allow information to be received by remote centres
  • 4. Telemedicine
    • Telemedicine typically involves medical personnel using   images, video and audio facilities either non-real-time (off line) or real-time (on line) for remote consultations. 
    • An expert physician far away can guide the local medical personnel in treatment planning remotely
  • 5. Telemedicine exchange of material offline
    • Store and Forward method
    • Local physician sending digital images of pictures, x-rays, and other patient information directly to the computer of a specialist.
    • After reviewing that information, the specialist then sends the diagnosis back to the local doctor, who treats the patient and provides follow-up care.

    • Limitation of image quality and size
    • Cross checking and feedback will take more time
  • 8. Telemedicine real-time (online) image transfer
    • Exchange of high quality still images, video clips between the remote center and   the experts using videoconferencing equipment.
    • experts outside will be able to guide the remote center in realtime
