Table 2.

Comparison of the performance of selecting consecutive frames with our frame selection method. “FS” stands for our frame selection method. The mean and standard deviation (in parenthesis) for each case is presented. The first column shows the experiment numbers which correspond to the following experiments respectively: Phantom, Pig Liver lesion 1, Pig Liver lesion 2, Pig Liver lesion 3, Pre-ablated tumor in patient, Post-ablated tumor in patient.
