Calculation of Intraclass Correlation Coefficients (ICCs). (a) Intra‐observer ICC (One‐way Random Single Measures, Agreement) – Comparison of Segmentations Drawn by Observer 1. (b) Interobserver ICC (Two‐Way Mixed, Single Measures, Agreement) – Comparison of Segmentations Drawn by Observers 1 and 2. (c) Comparison of the Three Spatial–Temporal Image Correlation (STIC) Volumes Using ICC (One‐Way Random, Average Measures, Agreement). Three Segmentations were Drawn on the STIC Volume, thus, Producing Three Sets of Volumetric Impedance Indices Per STIC Volume. An Average of These Three Volumetric Impedance Indices was Taken to Produce a Single Value that Represented Each STIC Volume.
