EFFECTS OF COLLAPSING CAVITATION ON HIFU-EXPOSED BIOLOGICAL OBJECTS

Therapeutic significance in the studies of HIFU-induced effects of is attached to the local heating of tissues, but the role of the mechanical component caused by non-stationary cavitation is practically not taken into account. Calculations show that the temperature inside cavitation bubbles can differ significantly from the temperature in the thermal ablation zone, and the developing temperature gradient can change the formation of the thermal field. Collapsing bubbles can cause mechanical destruction of tissues.
