Supplemental files Supplemental Figure 2.1: Recovery coefficients as a function of sphere diameter: uncorrected (A), IDC- LR (B), HH-GLBL (C), HH-LCL (D), spill-over (E), and PSF-reconstruction (F) of spheres in mediastinum, on noise-less images. Please note: RCs of A70PEAK exceed the y-axis maximum, up to 11.8 and 8.2 in graphs C and D, respectively. Missing values are due to failure of VOI delineation.
