UNDATED (CNN) -- X-Ray machines at airports that caused so much controversy among travelers are now being removed from major airports.

The Transportation Security Administration 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.
