A pencil beam of X-rays (11) is scanned over the surface of the body (12) of a person being examined. X-rays (16) that are scattered or reflected from the subject's body (12) are detected by a detector. The signal produced by this scattered X-ray detector (17) is then used to modulate an image display device (36) to produce an image (25) of the subject and any concealed objects car- ried by the subject. The detector assembly (17) is constructed in a configuration to automatically and uniformly enhance the im- age edges of low atomic number (low Z) concealed objects to facilitate their detection. A storage means is provided by which pre- viously acqired images can be compared with the present image for analyzing variances in and similarities with the present image, and provides means for creating a generic representation of the body being examined while suppressing anatomical features of the subject to minimize invasion of the subject's privacy.
