If I’m travelling with a backpack for example, and lay it flat , there will be around 15 layers at certain parts considering clothing, the separated compartments etc.
How can the display accurately display every overlapping item to the point where the people checking can be certain there is nothing prohibited within the backpack?
This may just be a stupid question but one which I’ve always wondered about so any answers would be appreciated 👍

Different substances reflect radiation at different levels. As the signals are sent through the items, a detector measures the different levels of signals being absorbed, and creates an image based on that.
