Cell Phones To Improve
the Quality of Telemedicine

Sure this is not kind of accessory that you’ll find in store near you but this 60x cell phone microscope attached on the Nokia N73 looks quite intrensting for me and my keyboard coludn’t resist to write soemthing about :]

University of California, Berkeley researchers have developed a modular, high-magnification microscope attachment for cell phones, enabling health workers in remote areas to take high-resolution images of blood samples and then transmit the photos to experts at medical centers.

Total cost of the very first prototype, built from off-the-shelf components, was just $75!!!

Researchers at the University of California, Berkeley, have developed a modular, high-magnification microscope attachment for cell phones. The device will enable health workers in remote, rural areas to take high-resolution images of a patient's blood cells using a cell-phone camera, and then transmit the photos to experts at medical centers.

The researchers hope that the innovation will help patients with blood disorders who live far from medical specialists get more accurately diagnosed and treated. "I wanted to make optical design relevant to today," says Daniel Fletcher, a professor of bioengineering at Berkeley. Fletcher's students found it relatively easy to integrate a simple arrangement of lenses with the cell-phone camera and transmit magnified images to a laptop using a Bluetooth attachment to the phone. The work prompted Fletcher to file a patent through the university and try to make a practical microscope. The researchers say that the cameras in late-model phones are capable of capturing all the details that a doctor would need to identify malaria parasites and cancer cells.

"The challenge was to make a low-cost, durable device with a long battery life," says David Breslauer, a graduate student in Fletcher's lab. "As engineers, we initially wanted to make a whiz-bang gadget to take pictures of both skin and blood. But people in the field told us, 'Once it gets too complicated, no one is going to want to use it. Make something simple that just does the task.'"
