Product overview
The C8 is a general-purpose portable colour Doppler system built around a 12.1-inch high-resolution colour LCD. Its imaging set covers 2D greyscale, colour Doppler enhancement, power Doppler, PHI pulse inversion tissue harmonic imaging with frequency compounding, spatial compounding, independent linear probe steering, speckle noise reduction, linear trapezoidal extension, convex extension, B/Color/PW triplex and panoramic imaging.
Measurement covers distance, area, circumference, volume, area ratio, distance ratio, angle, S/D velocity, time, heart rate and acceleration. On the obstetric side it handles fetal data for three or more fetuses, with fetal weight formulae, growth curve display and fetal echocardiography measurements including left ventricular function and left ventricular mass.
The system runs on a PC platform and weighs 4.5 kg net. A dual power supply with a built-in high-capacity lithium battery gives 2 hours of operation on battery alone, with the charge level shown on screen. Cold start takes 39 seconds, and two zero-insertion-force metal probe connectors are provided.
