In this latter case, at least the correct center of rotation needs to be known to ensure high quality tomographic reconstructions.
Once the correct center point and radius of the Newton diagram is found following the procedures outlined in section "Challenges in determining the center and radius of the scattering image", DCS extraction procedures as used and described by others can be used [6 9].
We vary the distance from the correct center, the offset, from 20px to 120px.
We also vary the angle of the line connecting the correct center and the initial center, the offset angle, by 45 degrees to a full turn.
More insight into the ranking of these methods could be obtained by studying the theoretical bounds for their performances, for example by computing their performances using the correct centers of the clusters and covariance matrices used to generate the training data.
The corresponding amplitude and the phase profiles after correct centering of the filtered angular spectrum and numerical propagation to the object focus distance are shown in Fig. 3c) and Fig. 3d).
The evaluation was focused on the correct centering of the targeted site, the presence or absence of perforation, the drilling depth, the deviation of the vestibulolingual direction relative to a reference axis on the control model, the deviation of the mesiodistal direction relative to a reference axis on the control model, the global drilling time.

Together, these rules defined a correct cyclical sequence of food-well visits (Figure 2C): right, center, left, center, right, center, left, center, etc.
Advancement of the subscapularis tendon over the graft, effective closure of the anterior pouch and a posterior shifting of the humeral head in a correct position centered on the glenoid socket could be clearly visible and assessed by arthroscopic examination from the posterior and antero-superior portals (Fig. 9).
To correct for phase center variation of both the GEONET and GNSS satellites, we applied the absolute antenna phase center variation table provided by the International GNSS Service IGSS).
