A Bland–Altman plot on the difference between mean absorbed dose. Mean of the difference is depicted by the black solid line, while black dashed lines show limits of agreement. B linear correlation plot between manual and automatic segmentation of the healthy liver VOI with respect to the mean absorbed dose. The solid line depicts linear regression (R² = 0.92), while the dashed lines indicate the ± 95% confidence intervals. Dotted line represents the x = y line. ¹⁶⁶Ho pre-treatment images were scaled considering the therapeutic activity
