Frequency-dependent considerations in simultaneous displacement and temperature estimation. The sequences consisted of interleavead HMI displacement and TSI temperature estimations for (a) 1.10 MHz using Ispta = 207 W.cm−2 and E = 33 J.cm−2 (4 cycles) and 83 J.cm−2 (10 cycles) and (b) 3.57 MHz, using Ispta = 34 W.cm−2 and E = 5.4 J.cm−2 (4 cycles) and 14 J.cm−2 (10 cycles). The 4 or 10 AM cycles at 25 Hz resulted in pulse durations of 160 ms or 400 ms, respectively.
