Claim 11:
12. A transrectal high intensity focused ultrasound (HIFU) device, comprising:
a boiling histotripsy (BH) ultrasound probe having a generally rectangular therapy transducer configured to emit therapy ultrasound in an ultrasound frequency range of 1 MHz to 2.8 MHz at a surface acoustic intensity of the ultrasound probe in a range of 10 W/cm2 to 80 W/cm2, the therapy transducer being about 50 mm long and about 35 mm wide and having a centrally located opening, wherein the therapy transducer is configured to generate shock waves at a focal depth of 2.5 cm to 5.5 cm, and wherein the therapy transducer is configured for mechanically disintegrating a target tissue by interactions between at least one mm-scale bubble and the shock waves, wherein the interactions take place within a duration of a pulse, without thermally damaging a surrounding tissue.
