Tests of cancerous K-562 and U-937 cells and healthy CD4 T-cells at a peak negative pressure of 0.7 MPa and a time of exposure of 60 s, showing the effect of frequency and pulse duration (PD) on cell-death rates. In all cases, the pulse duration is 10% of the total pulse repetition period. (a) Cell-death fraction versus pulse duration, and (b) cell-death fraction at 20 ms pulse duration versus type.
