A: data plot shows linear attenuation coefficient (LAC) values (mean ± standard deviation (SD)) in MR-based patient µ-map acquired with diagnostic setup that were determined within the respective tissue class segments in the RT µ-map. B: relative fraction of each tissue class within the RT (red) and the diagnostic µ-map (gray). Error bars are shown in light color, respectively, and represent 1 × SD. C: axial view of MR-based µ-map of one patient (#02, RT setup) with segmented tissue classes.
