This beamformer is used to compute SA beamformation. As the graph is obtained by the composition of L2 libraries, it has the summation of the components in I/O of the L2 libraries:
- Graph Inputs:

- directions: X-Y-Z values of propagation of the spherical or planar wave emitted;
- samples_arange: array with the index of the rf-data;
- image_points_from_PL: the result of Image Points;
- image_points_from_PL2: the result of Image Points;
- tx_def_ref_point: X-Y-Z array with the reference point of the investigation for that iteration;
- tx_def_delay_distance: X-Y-Z array that represents an absolute distance with respect to the focus;
