Table 2.

Metrics for ablation volume assessment including tumor volume, percent tumor volume coverage, percent target volume coverage, DSC, thinnest margin, and follow-up results. For cases with recurrences, the minimum distance between the insufficient margin to the recurrence is also shown. Note that the thinnest margin between 0.0 mm and 1.1 are shown as “≤1.0”, because the margins were calculated based on a 3D distance map with 1-mm isotropic voxels; the minimum non-zero distance in such a distance map was 1.0.
