(a) Percentage of maximum displacement tracked in the focal zone in materials with Young's moduli of 8.5, 23, and 58 kPa at times ranging from 0.1 − 0.7 ms after radiation force excitation. Note that accuracy of maximum displacement estimation improves more rapidly for the stiffer material (E = 58 kPa) than for the more compliant media. (b) Jitter decreases with time for all media and is greater in the more compliant media due to greater displacement magnitudes and slower shear wave speeds.
