Tissue-Based MRI Intensity Standardization: Application to Multicentric Datasets

Figure 3

Natural logarithm of the joint intensity histograms obtained for Subject 1 at Site 1, whose images are presented in Figure 2, (a, c) before and (b, d) after standardization with (a, b) and (c, d) STI. In (a, c), we overlaid the intensity mapping functions obtained with (a) and STI (c). The histogram diagonals (white) represent perfect intensity correspondence.
