Title:
COHERENT SCATTER IMAGING
Document Type and Number:
WIPO Patent Application WO2006027756
Kind Code:
A3
Abstract:
A region of interest is identified using a conventional CT or X-ray approach. Then, the region of interest is scanned using a plurality of pencil beams (28) to obtain a plurality of different scattered X-ray spectra. A geometric correction is then applied to each spectrum as if the spectrum was solely due to features in the region of interest. The various spectra recorded using the beams are combined and correlated to determine features of the region of interest (32) whilst minimising the effect of features in the rest of the sample (30).
