Body Cavity Scanners
At least one company is touting its technology:
Nesch, a company based in Crown Point, Indiana, may have a solution. It’s called diffraction-enhanced X-ray imaging or DEXI, which employs proprietary diffraction enhanced imaging and multiple image radiography
Rather than simply shining X-rays through the subject and looking at the amount that passes through (like a conventional X-ray machine), DEXI analyzes the X-rays that are scattered or refracted by soft tissue or other low-density material. Conventional X-rays show little more than the skeleton, but the new technique can reveal far more, which makes it useful for both medical and security applications.
