Abstract

Disclosed are a method and apparatus for tomography of a curved surface in an object. One embodiment is a method that includes determining an expected distortion for each of a plurality of points in a projection of the curved surface, and correcting each of the plurality of points in the projection according to the expected distortion of that point by replacing pixel values in the uncorrected projection with corresponding interpolated pixel values at the expected positions.
