So this all started last year, but TSA is really starting to use these scanners now. Basically, they pick people out of the airport security line “at random” and let them choose between going through the body scan (which takes like a minute) or submit to a pat down. You are not taken to a private room for this, it’s done right by the metal detectors. TSA agents view the images and TSA claims all images are immediately deleted after they are viewed.
I feel that there’s a lot of leeway here for misuse. Who is to say the TSA agent calling people out of line isn’t a pervert/pedophile/whatever choosing people who he/she finds attactive or especially ugly or fat? And are there multiple TSA agents sitting there with popcorn chuckling at these people’s naked bodies?
Personally, I think that if there wasn’t such outrage in the beginning, TSA would consider making this body scan mandatory for all travellers. After all, it’s been designed to take less than a minute.
So the questions:
Do you think it’s an invasion of privacy?
Which would you choose, the body scan or the pat down?
If the body scan were made mandatory at some airports, would you go out of your way to avoid those airports? Say there’s another airport an hour away, would you drive to that one instead?
Any other comments?
You can see the body scan images here:

It is like a virtual strip search. The flaw with this system is that it gives body parts in high clarity. In other words, to the person behind the computer, you would be naked.
Safeguards? This person viewing your full body scan will be in another room, and will never get to see you in person.
Possible Problems? There are cameras within the airport. Hypothetically, One can see the time of the image taken, and then view the video taken at that time. The video clip, and the image can then be placed online, for millions to view.
Hm… For the sake of security, I support it. I’d rather risk my privacy, then my safety.
How about you?
As a MRI Technologist with 15 years experience in diagnostic imaging, I can assure you beyond a reasonable doubt that the “body scan” machines will be virtually useless in detecting explosives.
Let me explain why. The macines use radio frequency “millimeter waves” to detect what’s hiding under your clothing. It is very similar to radar in that it bounces a pulse of rf at a 3d target and then a computer compiles the data into a 3d image that you can “see”. The reason it won’t work is because it only does a surface rendering of the object. Thus, if a pliable explosive were used and molded to the body or placed in a skin fold the scanner would never see it. Theoretically, you could smuggle literally POUNDS of high explosives through one of these gadgets without notice. What “will” work? Xrays in the form of a tomographic scanner. But that’s not going to happen because of the radiation dose and the cost. So, who benefits from body scanners? ahem….. General Electric and their ilk.
Take it or leave it. That’s the stone cold truth boys and girls.

Truthseeker, I’ll have to disagree with you on two points. First, backscatter machines like millimeter waves only offer a surface rendering. If you want to have contrast of density then you must use higer doses. Secondly, the dose in minute? How minute? How much exactly is “safe”? Perhaps you should google the Linear Non-Threshold Dose response relationship involving xrays. There is no “safe” dose.
What should I look for? I need to scan and print some art images to submit for my producers. Some of the art has very fine lines close together. Most of them are sketches and drawings using pencils and pen on paper with not much color used. Some of it is also water paintings done by local artists. I want to capture color and just as importantly, detail. When the sketch prints out, it’s important that if a magnifying glass is used, there shouldn’t be much, if any at all, detail loss. As far as scanners go, I assume I just look for high resolution capability? Cost is somewhat important as well, I’m trying to stay within the $500 budget range. Thank you everyone in advance.
What’s best for micro printing? Anything that can print micro text or numbers should be fine capturing the details of the art. Colors should match up well too of course.

I work in a CVS Photo Lab. I’ve been developing my own 35mm color film for a while, but I recently started shooting 120 film. Our film machine will run the 120 just fine as long as it’s C41, but our scanner/printer (Noritsu QSS-3011) only accepts 135 and APS. I was wondering if there are any mini-lab scanners that can transfer 120 to digital.
Full body scanners in airports: necessary for safety, or invasion of privacy?
With full body scanners operating in some of our nation’s airports now, the debate over what is safe and what is appropriate is going on across the country. Albany Law students examined the issue Tuesday night.
