      • commercial software available
      • SAGA and Peradeniya Activity
    • 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
    • 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
    • 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.
    • Telemedicine - non realtime store and forward method
      • Usage
      • Teleradiology
      • Telepathology
      • Teledermatology
    • Telemedicine- non realtime store and forward method
      • Advantages
      • Minimum resources needed
      • Regular email attachments could be used
      • Disadvantages
      • Time delay in response
      • Limitation of image quality and size
      • Cross checking and feedback will take more time
    • 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
    • Telemedicine : real- time
      • Advantages
      • Used in many areas of medicine, surgery, dentistry
      • accessibility of expert help in remote areas
      • Saves time of an expert in frequent travel to remote areas
      • permits Continuing Education and training for practitioners in remote areas
      • Disadvantages
      • Non availability of appropriate technology and adequate bandwidth in the network
      • Lack of funds for equipment and software
      • Lack of technical help
    • Basic requirements

    • Shortcomings of commercial software
      • Eg:- Messenger. CuSeeMe, Netmeeting,, freetalk,
      • Poor quality of images at low speed networks
      • not suitable for medical collaboration activities
        • image manipulation, tele-pointing facility on the image canvas, shared-board
      • clinicians would prefer a user-friendly operating environment specifically designed for medical applications.
    • Sri Lankan Experience of high quality medical image and voice transfer through internet Between Medical School & Faculty of Engineering SAGA University-Japan And Faculty of Dental Sciences - Peradeniya Department of Oral Surgery Faculty of Dental Sciences, University of Peradeniya
    • Previously used method - Store and Forward
      • Images of patients- photographs and radiographs were exchanged
