Although many CT systems use the FDK method to solve the 3-D image reconstruction task, it is not without its short-comings. Therefore, we have described in Section 2.3 two alternative approaches: the theoretically exact and stable M-line method applied to a short-scan circle-plus-arc acquisition (Section 2.3.1) and the simultaneous algebraic reconstruction technique as a representative of the iterative approaches (Section 2.3.2).
