Of course, there are lingering privacy concerns over previous clothing-penetrating scanners. The Department writes that the new ATR system replaces photographs of the person in the machine with a generic body, indicating where possible foreign objects are on the image. If any appear, that's when a further physical search will be conducted. Automatic Target Recognition apparently can't store any images and the DHS says that the AIT gear "does not generate or retain an underlying image of the individual." Moreover, the physical scans will only target the area on a person's body where it's indicated the contraband is. If there are multiple alerts, a full screening might take place. So that's settled at least.
