Method for the localized destruction of soft structures using negative pressure elastic waves

摘要

The method for the localized destruction of soft structures using negative pressure elastic waves, comprises the steps of generating at a predetermined rate comprised between a few Hz and 3 KHz, trains of elastic pressure waves, said waves having a frequency between 0.3 and 10 MHz, each of said trains having a duration between 1 microsecond and 1 millisecond and comprising negative going oscillations; focussing said waves into a beam; transmitting and directing said beam onto the target through a liquid coupling medium and adjusting the power of said elastic pressure wave at a predetermined value.
