JaxBill,
Thanks for the link. All Rapiscan Secure 1000 single pose AIT scanners will be removed from US airports on or before the 1st of June 2013. The removal of these scanners does not eliminate backscatter as new contracts for replacement scanners are being issues for both millimeter wave and backscatter. These new AIT scanners incorporate the Automated Target Recognition software which offers more passenger personal privacy as well as an easier interface for operators.
Personally l'd like to see the TSA revisit the Iscon thermal AIT scanners. The agency previously purchased roughly 20 of the the 1000D models trained TSOs on them , then shelved them in favour of additional Rapiscan Secure 1000 scanners. The Iscon thermal AIT scanners emit no radiation,had a significantly lower false alarm average and had comparable processing speeds.
