McCarran airport getting new advanced carry-on scanners

Some carry-on bags at McCarran airport will soon be scanned with the same type of technology used by hospitals for medical images. CT imaging is already used to screen checked baggage. The scanners will be deployed to McCarran and 14 other U.S. airports in the next few months, allowing the TSA to see items more clearly. Each machine costs at least $350,000. Over time, the TSA said it expects processing to be faster. The technology may someday allow travelers to keep liquids and laptops in their bags.
