More marvels of electronics that await us. Now and the doctor can sit in the doctor's office and sen what your heart is doing, maybe.

General Electric Co. CEO Jeff Immelt, Tuesday gave an audience at the Web 2.0 Summit in San Francisco the first public viewing of the company's new pocket-sized device, dubbed Vscan, that's designed for point-of-care imaging.

Though Immelt couldn't say how much the Vscan will cost, he said he's hoping a much lower price tag than traditional medical imaging machines while getting the technology into the hands of doctors around the world.

"It's the stethoscope of the 21st Century," said Immelt. "It's an ultra sound the same size as a Blackberry with the same power that an ultrasound would have two to three years ago sold for $250,000.

Immelt said he's hoping the pocket-sized device can help redefine the physical exam. Because it's expected to much less expensive and easier to handle than a traditional ultrasound machine, he's hoping doctors will be able to directly get more information about what's happening inside a patient.

"We can monitor the heart and see what else is going on inside the body. See if a baby is breach" he added. "Putting ultra sound tools in doctors' hands is very important for GE. It's about miniaturization and power."

The Vscan, which was developed across 10 or 12 GE global design centers, has been granted 510K clearance by the U.S. Food and Drug Administration, which means GE has successfully notified the government of its intent to market the device. The company has not said when the Vscan might be available for clinical use.
