Abstract :
Conventional computed tomography (CT) produces “maps” of the X-ray linear attenuation coefficient within a slice through an object. A novel approach to CT is being developed which instead images an object´s low-angle (0-10°) X-ray diffraction properties. The coherent-scatter cross sections of many materials are distinctly different, and this coherent-scatter CT (CSCT) system gives material-specific information on this basis. The goal of this research is to produce tomographic maps of bone-mineral content (BMC), first in laboratory specimens, and potentially in patients
