The direct problem of data acquisition from detectors and the inverse problem of image reconstruction
Abstract
The problem of image reconstruction is examined with particular reference to nondestructive testing applications. A method is proposed for recording projection data in various regions of the spectral range of the transmitted radiation. The data acquired in this manner are subsequently used for correcting the final solution obtained by using a matrix inversion algorithm.
