Paper Abstract

The determination of spatial structure density of inhomogeneous medium iising X-ray computer tomography is reduced to the solution of Radon integral equation G(y0,8) = J n"()do , (1) where n"() is the absorption coefficient (an imaginary part of the complex refractive index n=n'+in", n'=l), which is proportional to the medium density. Integration in (1) is done along straight rays y0=const, and G(y0,8) is a measurable function, i.e. an integral absorption along the rays, inserting the object at view 0, '2
