Subject: [ RadSafe ] Z-Backscatter technology


Does anyone know how I might get ahold of technical information on the Z-Backscatter technology as used for example by the AE&S vans mentioned in the above article? I am especially curious as to how the image of the contents of a vehicle is not obscured by backscatter off of the sides of the van and of the vehicle being scanned. Both the beam and scattered x-rays must pass through both vehicles on the way out and back. Also I'm curious about the density information presented in the images of people within a trailer. They appear to show the individuals lungs as dark regions within the thoracic cavities. I would not expect this from a backscatter image.
