Figure 6.

Representative images from breath-hold ablation experiments. During a single breath-hold, MR-ARFI was performed at a focus, immediately followed by a thermal ablation. The MR-ARFI image of the focus (left, in micrometer) was compared with the subsequent thermal ablation (right, measured as °C temperature rise). The horizontal line highlights that the foci align. The standard deviation of the discrepancy between displacement focus and thermal focus in the L∕R and S∕I directions for all seven breath-hold ARFI∕ablation comparisons was 0.83 and 0.99 mm, respectively (see Table TABLE I.).
