METHOD AND APPARATUS TO FACILITATE PROVISION AND USE OF MULTIPLE X-RAY SOURCES

摘要

One provides (101 and 102) two or more X-ray sources (202 and 204) that are independent and discrete from one another. By one approach, these X-ray sources emit corresponding X-rays (203 and 205) 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.
