The Transportation Security Administration introduced full-body scanners at airports across the nation in 2009, and many travelers hate that a "naked" image of themselves is reviewed by officers in a nearby room.
The only way to avoid the image process is to instead undergo a physical screening by a TSA officer, which some travelers say can be just as invasive.
Now a new generation of scanners is emerging that will display "Gumby"-like images of passengers rather than today's more detailed passenger-specific snapshots, as pictured at left.
Boston Logan International Airport will be the first U.S. airport to use the new advanced imaging technology (AIT) body scanning machines during the next two months.
By the fall, all 25 of the Boston airport's current scanners will be swapped out with the new machines. And more airports will see the new units in the coming years.
