> yes, resonance can be significant, but that still doesn't necessarily mean that the energies here are significant, nor that the frequencies applied are the right frequencies, and resonant enough, for damage. I did not claim that the proposed method has to be harmful. I stated that ultrasound imaging gives little to no insight in what happens at frequencies that are an order of magnitude or two higher than that. The second reply was an attempt to do away with the misconception that "higher flux of energy" was necessary for damage.
