ABSTRACT:
One provides (101and102) two or more X-ray sources (202and204) that are independent and discrete from one another. By one approach, these X-ray sources emit corresponding X-rays (203and205) using different voltage levels. In particular, these voltage levels can be sufficiently different from one another to readily permit different elements as comprise an object (201) being examined to be distinguished from one another. These X-rays are then emitted (106) from these sources and towards an object to be examined while causing relative motion (207) between such sources on the one hand and the object on the other.
