Most of the telemedicine applications in use today are made up of two different kinds of technology. The first is called 'store and forward'. It is used to transfer digital images from one location to another. A digital image is captured by a digital camera (stored) and then sent (forwarded) to another location. This is used for non critical situations where a diagnosis or consultation may be made in the next 24 to 48 hours and sent back. Data and images may be transferred from any part of the world to any location anywhere in the world provided the two locations are connected via any telecommunications medium. Radiology and Pathology images are the most commonly sent images in not critical cases.
