Photographs of sectioned porcine liver tissues after ablation. (a) Lesion produced by the SFUS with acoustic power input of 30 W and a duty cycle of 0.2 s on/0.2 s off for 50 s. Note: As indicated by the white arrow, a separate lesion was previously created from a different angle. (b) Lesion by the AFUS applicator with 20 W and duty cycle of 0.2 s on/0.6 s off/0.4 s delay for 140 s. (c) Lesion by the AFUS applicator with 20 W, a duty cycle of 0.3 s on/1.1 s off/0.7 s delay for 110 s at the depth of 5 mm. (d) Lesion by the AFUS applicator with 20 W, a duty cycle of 0.3 s on/1.1 s off/0.7 s delay for 129 s at the depth of 10 mm. Note: The black arrows in (a)–(d) show the approximate direction of the incoming ultrasound beams. (e) Cross-sectional cut of the same ablation as (b) to show the shape of the lesion in three dimensions.
