An example (patient ID BI04 from training set in our database) of transaxial and coronal view of non-rigid registration evaluation for a patient with Likert score of “little misalignment,” the statistics [min, Q1, median, Q3, maximim] of the Jacobian over all liver voxels, eroded liver, and excluded liver for this patient are [0.42, 0.82, 0.89, 0.97, 1.74], [0.58, 0.83, 0.88, 0.96, 1.45], and [0.42, 0.82, 0.90, 0.99, 1.74], respectively, (red contours are from the excluded liver and eroded liver—see b): a reference image CTMAA, b excluded and eroded liver: eroded liver is manual liver segmentation eroded by 10 mm and excluded liver is the subtraction of excluded liver from liver c and d results of non-rigid registration (CTFDG to CTMAA) and the deformation grid and e Jacobian determinant of the non-rigid registration: blue, local dilation; red, local contraction; and white, no local volume change
