(a) Example lesions generated in liver through different thicknesses of tissue between 18 – 70 mm. Lesions contain a similar appearance of mechanical liquefaction of the tissue without thermal necrosis. (b) Data showing occurrence of boiling in tissue for different transducer driving voltages and depths. The grey-shaded area encompasses the range between lower and upper bounds for the predicted derating curves based on time-to-boil calculations. Boiling is expected to occur when VDC is greater or equal to a threshold estimated in the grey region.
