One of the reasons that the TSA has used for having both MMW and BKSX is that by having two suppliers, they are not locked into using only one vendor who can increase price at will. Due to patent issues, there aren't multiple manufacturers making MMW devices.

If it would see full cavity it would likely need to be transmission Xray, not backscatter. These are used in prisons and customs but need even higher doses.
My theory is that the TSA's backscatter machines can be adjusted to emit transmission Xrays, which would permit full body cavity searches, and that is why TSA prefers backscatter machines over MMW machines. |

The only difference between transmission Xray and backscatter Xray is the wavelength of electromagnetic radiation being emitted.

That said, check out the last sentence in the Propublica article: The TSA plans to deploy 1,275 backscatter and millimeter-wave scanners covering more than half its security lanes by the end of 2012 and 1,800 covering nearly all lanes by 2014. This is not good enough at all!!! Enough is enough!! They aren't allowed to install the bodyscanners at airports anymore! |

What am I missing here? The MMW machines don't have the ionizing radiation issues that backscatter does, so why aren't they just installing those, heading off the "health issues" part at the pass and then addressing the privacy issues w/ the cartoon image?
I mean, I understand there will be opposition to the imaging technology among some people regardless of what they do--I merely speaking to the idea of how could the TSA implement a plan that would still get most opponents to come around? For me, it would take: 1) MMW only 2) Stop the "Freeze! Put your hands up!" criminality routine 3) Use the cartoon image (sorry the true term/acronym is escaping me at the moment) 4) Reduce the false positives or at a minimum, after a false positive, only have a patdown/quick frisk of the suspect area be completed vs a grope. They do that, I think that would be fairly reasonable (although not ideal--I understand an ideal of just x-raying the bags and walking through the WTMD is never coming back). |

Sorry, since the machines cannot detect material density, #4 can NEVER happen. That is a fact.
