It's sort of an all-or-nothing proposition. For it to look through clothes, it has genital resolution. Allegedly the images are automatically erased after either 24 hours or right after the person leaves the imaging chamber. They say that the system has already been modified to de-rez or obscure genitals and faces without losing the detection of hidden weapons. And theoretically the operator is in another room and cannot see the person in the imager, so maybe the perv factor is diminished.
