Abstract

A method (200) for determining grain structure in a component (102) includes disposing the component (102) on a support platform (110). The method (200) includes generating an imaging beam (106). The method (200) includes rotating and/or revolving an imaging beam source (104) and an imaging beam receiver (108) relative to the support platform (110). The method (200) includes acquiring, during the rotation and/or revolution a plurality of projections (116) each taken at the imaging beam receiver (108). The method (200) includes performing reconstruction, by a processor (114), of first projections (116-1) and second projections (116-2) from the plurality of projections (116) to obtain a first three-dimensional image (120) and at least one second three-dimensional image (122). The first projections (116-1) are acquired in at least one first angular range (AR1) and the second projections (116-2) are acquired in at least one second angular range (AR2).
