In vitro and in vivo ablation of porcine renal tissues using high-intensity focused ultrasound

摘要: The aim of this paper is to present issues regarding the thermal ablation porcine renal tissues in vitro and vivo using high-intensity focused ultrasound (HIFU). Production lesions cortex consistent, whereas medulla are created whenever there no air spaces medulla. Typically, lesion length at 2000 W/cm2 5-s pulse duration around 20 mm corresponding width 3 mm. Lesioning a large volume was achieved by moving transducer grid formation. through fat layer possible provided that between kidney interface. It found that, above 3200 with 4 MHz, cavitation activity occurred most created.
