(CNN) -- X-Ray machines at airports that caused so much controversy among travelers are now being removed from major airports. They are in a box-shape, called "backscatter machines.”
The Transportation Security Administration (TSA) is replacing them with newer machines.
The website Pro-Publica is reporting those X-ray body scanners are being removed from high-traffic airports like LAX, DFW, JFK and Chicago O'Hare -- and moving them to smaller airports.
X-ray body scanners got a bad rap from travelers over privacy because the X-ray images could be revealing.
According to Pro-Publica, the new machines known as millimeter-wave scanners display a generic drawing of a person's body, instead of a detailed body scan image.
TSA officials say the new scanners will streamline the process and get travelers through security quickly.
