Comparison of the image reconstruction quality evaluated using R-factor and PRTF. (a, b) Average R-factor values obtained from all seed images (a) and from the five best images selected based on the lowest reconstruction error (b). Lower R-factor values indicate higher consistency between reconstructed images. Brown and green points represent results from the SASE and SS beams, respectively. (c, d) Spatial resolution estimated from the PRTF, calculated from all images (c) and from the five best images (d) after alignment and averaging. The resolution was determined based on the 0.5 PRTF criterion. In both evaluations, the SS beam consistently demonstrated superior reconstruction reliability and higher spatial resolution compared with the SASE beam.
