Fig 3. Lesion volume in tissue-mimicking phantom for varying BH sonication parameters.

Fig 3

a. Lesion volume did not vary significantly for acoustic power 500–650 W at constant PRF of 1 Hz (p>0.05, ANOVA). b. Lesion volume with varying cycles/pulse. Significant differences (p ≤ 0.05) in lesion volumes were found between 10,000 and 18,000 cycles/pulse as well as 10,000 and 20,000 cycles/pulse. c. Varying total sonication time between 137 to 820 seconds resulted in no significant differences (p ≤ 0.05). d. Pulse repetition frequency (PRF) was varied from 0.5 to 5 Hz. The lesion volumes were significantly different between 0.5 and 3, 4, and 5 Hz (p ≤ 0.05). Similar differences were found between 1 and 3, 4 and 5 Hz, as well as between 2 and 4 and 5 Hz (p ≤ 0.05).
