The MAE for the whole-HN region with respect to different crop and stride parameters, as well as effects of clipping the MR input intensities to the 99 percentile value for the image, or for a static post-standardized value for the external test set. This plot shows that when multiple sCT estimations overlap and are averaged, either by using three complementary views or overlapping patches in a single view, the errors decrease, and that standardization prior to sCT generation improves MAE.
