Considering Angle Selection When Using Ultrasound Electrode Displacement Elastography to Evaluate Radiofrequency Ablation of Tissues
Figure 6
Comparisons between the meatball sizes and the ablation zones detected by electrode-displacement strain imaging (). (a) angle = 30°, (b) angle = 40°, (c) angle = 50°, (d) angle = 60°, (e) angle = 70°, (f) angle = 80°, and (g) angle = 90°. The correlation coefficient decreases with increasing the angle between the transducer and the RF electrode. No significant correlation was found when the angle was larger than 60°.
