Telemedicine is the practice of medicine over communication links. The physician being consulted and the patient are in two different locations. A first telepathology system has been developed by Corabi Telemetrics. It allows a pathologist to render a diagnosis by examining tissue samples or body fluids under a remotely located microscope. Of course it would seem natural to digitize the entire specimen at the highest magnification and then leisurely explore the transmitted image. But this is not currently practical because the specimens are very high definition 3D color objects requiring too long to digitize and having impractical storage requirements. Therefore the specimen still needs today to be explored under a microscope.
