1,Acurate Localization:With appended head , Ultrasound localization becomes easier. 2,Longer therapy depth: With a 135mm therapy depth ,the treatment of the Obesity becomes more convenient. 3,Wider Aperture:A wider Aperture(200mm)gives more energy in breaking stones. 4,Lower pressure:Under the range of 3.5-6.5KV,one can feel less pain or even painless. 5,demountable electrode holder:It allows you to change the electrode more easier without draining the water and uncovering the cushion. Specifications: Range of discharge voltage 3.5-6.5kV Peakpressure 20-50MPa Lateral diameter of focus area 10-15mm Discharge energy 12-36J Discharge energy 12-36J Front of the peak pressure pulse ¡Ü0.2¦ÌS Width of half peak pressure ¡Ü1.0¦ÌS Triggering mode manual, auto., respiration and ECG Life time of the electrode ¡Ý4000 times Movements of therapy table 100mm in Y direction 100mm in X direction 140mm in Z direction Rotation of US localization around therapy head 360.
