FIGURE 6.4: On the left, individual projections are shown with the top
row before and the bottom row after automatic motion correction. Please
note the change in position of the patient during the acquisition of the second
projection shown. Correction is based on a center of mass calculation on a part
of the projection, where discontinuities in the sinogram and linogram can be
detected.
