Body scans

Any imaging technology that shows parts of the human body that are usually hidden, for instance brain imaging, fMRI, ultrasound, x-ray, or body scans in airport security that show objects under clothing. Includes cameras probes that enter the body. Does not include cameraphone apps for diagnosing melanomas, as the melanoma is not hidden but visible to the naked eye. Would include headbands for meditation that visualise brainwaves, as these are not normally visible.
