1. A method of performing x-ray analysis on a body of unknown composition, the method comprising:
- bombarding the body with a plurality x-ray beams, each x-ray beam having unique line spectra; and
determining the compositional makeup of the body by detecting and analyzing x- rays reflected off of the body.

Abstract
An x-ray generator capable of generating multiple selected spectra of x-rays to penetrate an object being studied is described. An x-ray detector designed so as to detect and/or image different x-ray spectra selectively is also described. Undesired spectral components can be rejected, and desired spectral components accepted for detection and/or imaging.

18. A method of analyzing x-rays reflected off of a body under study, the method comprising:
-
illuminating the body with x-ray radiation;
filtering the x-rays reflected off of the body using a first spectral filter;
imaging the body utilizing the x-rays filtered through the first spectral filter;
filtering the x-rays reflected off of the body using a second spectral filter;
imaging the body utilizing the x-rays filtered through the second spectral filter; and
comparing the similarities and differences between the images to estimate nuclear densities of materials in various locations of the body. - View Dependent Claims (19, 20)
