WebJan 1, 2024 · 1. Introduction. Boiling histotripsy is a High Intensity Focused Ultrasound (HIFU) technique that employs a number of millisecond long HIFU pulses with high peak positive P + and negative P-pressures at the HIFU focus (P + > 40 MPa and P-< 10 – 15 MPa). This results in mechanical tissue fractionation without causing any significant … WebBoiling histotripsy is a promising non-invasive High-Intensity Focused Ultrasound (HIFU) technique that employs HIFU mechanical effects to …
