(a) Exemplary display of a segmented ablation. Initially, all ablations were bisected at level of the center of the active zone of the antenna to achieve the largest cross-sectional area. Starting from the center (0), each ablation half contained a maximum of ten additional segments (+/- 20). (b) The antenna (A) and vessel (V) were identified and the WZ and RZ outlined manually in each ablation segment. The software then calculated respective ablation radii. In clinical practice, a microwave ablation ideally covers the liver tumor completely (green sphere). Cooling effects, however, can lead to discrepancies of the expected minimal radius and the actual minimal radius (cf. Fig. 1).
