Add Savannah to the list of U.S. airports using body scanning technology to screen passengers.

The Transportation Security Administration will hold a news conference Wednesday at the Savannah/Hilton Head International Airport to discuss the new body scanners, which were installed in the past week.

The scanners use imaging technology to search passengers for explosives and other contraband. Early versions drew howls of criticism for being too intrusive, as they effectively produced a digital image of a person's naked body. Upgraded machines like those being used in Savannah use a generic silhouette instead, and passengers can see the image along with security screeners.

In all about 165 airports nationwide are now using the body scanner. Hartsfield-Jackson Atlanta International Airport was among the first wave to install the machines.
