Identification of nonlinear beam-hardening effects in X-ray tomography [PDF]
arXiv, 2023 We study streaking artifacts caused by beam-hardening effects in X-ray computed tomography (CT). The effect is known to be nonlinear. We show that the nonlinearity can be recovered from the observed artifacts for strictly convex bodies. The result provides a theoretical support for removal of the artifacts.

Adaptive zooming in X-ray computed tomography [PDF]
Journal of X-Ray Science and Technology: Clinical Applications of Diagnosis and Therapeutics, 2014 BACKGROUND: In computed tomography (CT), the source-detector system commonly rotates around the object in a circular trajectory. Such a trajectory does not allow to exploit a detector fully when scanning elongated objects. OBJECTIVE: Increase the spatial resolution of the reconstructed image by optimal zooming during scanning.

3-D X-Ray Computed Tomography [PDF]
, 1986 Though well established in medicine as a technique of inspection, x-ray computed tomography (CT) is just beginning to have an impact on nondestructive evaluation. A recent review [1] emphasizes the potential of the technology. An aspect which is apparent
