It might look more like a Radio Shack project kit than a serious piece of medical equipment, but George K. Lewis -- a third year biomedical engineering PhD student -- has developed a pocket-sized ultrasound device that can be manufactured for about $100. Typically, a biomedical ultrasound unit can weigh 30 pounds and cost upwards of $20,000. The developer has high hopes for the device -- not only will an ultraportable ultrasound bring the technology to places where it might have been impractical before (such as combat units in the field and remote populations), hopefully the inexpensive contraption will spur innovative new uses for the device. So, what's stranger -- scoping your unborn child with a homebrew ultrasound, or using an incubator that once lived as a Toyota 4Runner? That's a tough call...
