But the advent of digital imaging has solved many of our troubles. Telepathology made sure that we do not need a pathologist physically present at the site, to render a diagnosis. But microscopy and digital imaging of the biopsy/tissue fragment was still a hassle. Now we have done better. You don’t even need a microscope to send a microscopic image over the network!!Researchers from the Univ. of California worked with high-powered LED – which retails for just a few dollars – coupled with a typical camera phone to produce a clinical quality image sufficient for detecting in a field setting some of the most common diseases in the developing world.

“The images can either be analyzed on site or wirelessly transmitted to clinical centers for remote diagnosis. The system could be used to help provide early warning of outbreaks by shortening the time needed to screen, diagnose and treat infectious diseases,” University of California in San Francisco (UCSF)/UCB Bioengineering Graduate Group graduate student David Breslauer adds
