Table 11. RT Projection from geometric analysis of PP (Table 10) along with normalization of the axis to keep AP intersection constant. Here we take the point source and plane data from Table 10, computed from PP, and then generate detector plane intersection. Because the detector plane is off-axis (not COA), a normalization procedure is computed as the corrected form, which forces all AP distances to a constant value (COA). Then the LAT/VERT of the corrected can be translated/rotated and positioned over the image.
