Outside of the clinical space, some X-Ray and CT systems use dual energy emmission to have better materials discrimination than you might think, as it isn't just based on density but also Z eff (https://en.wikipedia.org/wiki/Effective_nuclear_charge).

Also, there are units that don't spin the tube - an older system that spun a beam to hit a large, circular annode (only a single manafacturer), and at least one modern design that has hundreds of small emitters (https://www.rapiscansystems.com/en/rtt).

Cheers.

Yikes, they even admit it they are invested in both industries.
I guess all we have to do is prove they know it causes cancer and once the first victims come around they'll have a good lawsuit. Or I suppose an American regulator can put a stop to this (stop laughing). Isn't there some department in the USA that is supposed to investigate this kind of thing?

This is a scam.

These scanners were promoted by Michael Cherfoff, Head of Homeland Security under W.

Now he is CEO of the Chertoff Group, and is lobbying for Rapiscan, which makes these very machines at issue here. How convenient.

Their Secure1000 system claims to be active (from here): "The Rapiscan Secure 1000’s patented technology is composed of an ultra low-dose X-ray source that images backscattered X-rays through to a remote operator’s workstation."

Full body X-ray along these lines have been available for ages! I went through Gatwick nearly 5 years ago when they were trialling these :

Seems like the only really feasible solution - having said that, according to their press blurb the TSA have trialled them already!

Here are the web sites of the two companies mentioned in the article.

Rapiscan Systems

and

HiEnergy Technologies, Inc.

They both have interesting product portfolios.

AS&E also has a "drive-by scanner" in a van, for covert scanning. This is a higher powered device than the BodySearch. "Although radiation exposure levels are below those specified by the American National Standards Institute (ANSI), the ZBV is not certified as a personnel scanner. Customers planning to operate the system in stationary mode must obtain an exception from government regulations."

Slightly more practical is the RapiScan Secure 1000. It's less bulky than the BodySearch; it's only 80 inches high, so it can be installed with less trouble, although it weighs half a ton. And it only takes 8 seconds per scan. Like the BodySearch, it's a true backscatter X-ray machine, and produces good images through clothing.

Two more generations and these things will be in nightclubs. Here's a paper (in German) with picture of a cute girl seen with a BodySearch machine. So now you know what it shows.

In this sample image it's explicit enough they had to block it out.
