Therapeutic ultrasound transducer field simulation. a FIELD II simulation of pressure distribution for free field single-element therapy transducer. b Lesion formation based on the lesion-pressure dependence; volume narrows the region of lesion formation to where peak negative pressure is above 2 MPa, i.e., greater than the lesion formation pressure threshold. The acoustic pressure field representing the expected lesion region is 2.5 × 32 mm at the level of −6 dB relative to 4 MPa
