Wide Focus And Low Pressure

The conditions to fragmentation which called wide focus and low pressure are: maximum pluse positive pressure at the focal zone:10—25MPa;negative pressure:＜5 MPa;focusdimension:radial≤±10mm ,pulse width 1—2μS.The wide focus and low pressure enhanced the hit rate and energy, while improving the breakage efficiency .It made the treatment safer and more effective through reducing the harm to human body by negative pressur
