Table 2.
Accuracy, precision, and bias parameters of MR thermometry in all treatment sessions and the selected dataset based on the Jaccard coefficient threshold equal to 0.91. All evaluation parameters are expressed by the mean (µ) ± standard deviation (σ); these mean values are also indicated in light red circles in Figure 6 and Figure 7. The number of sessions and patients remaining after exclusion are indicated. In addition, the average deviation from the acceptable threshold is given for accuracy (1 °C), precision (1 °C), and bias (±0.5 °C). The equal values or below the acceptable threshold are in boldface and underline.
