METHOD AND APPARATUS FOR ANALYZING COMPUTED TOMOGRAPHY DATA

A method (100) of analyzing computed tomography data includes creating a mesh of a sampling surface that extends through a component (16) to obtain a meshed surface (82); creating a plurality of additional surfaces (90) that are different from each other and from the meshed surface (82), and that each correspond to one or more of a translation and a rotation of the meshed surface (82); querying an interpolant function, which is fitted to CT data (68) of the component (16), at a plurality of points (92) of the meshed surface (82) to project the CT data (68) onto the meshed surface (82); querying the interpolant function at a plurality of points (94) of the additional surfaces (90) to project the CT data (68) onto the additional surfaces (90); and determining, for each of the plurality of points (92) of the meshed surface (82), whether the point (92) is a void based on the querying for the meshed surface (82) and the querying for the additional surfaces (90).
