Phase Inversion Harmonic Imaging
Harmonic signals are produced as ultrasound waves propagate through the body. Because these signals are produced in the body, they are not influenced by artifact inducing fat near the skin surface. Consequently, an image formed using only the harmonic signal will have less clutter and can be more diagnostic. With phase-inversion harmonics, pairs of ultrasound pulses with opposite phases are transmitted. When the signals received from inverted pulses are added together, the fundamental components are cancelled and only the harmonic signal remains. This creates an image that is pure harmonic with reduction in clutter artifact that degrades the image.
Speckle Reduction Technology
Speckle reduction imaging uses real-time image processing to improve visualization of anatomy and pathology by reducing the speckle noise. Edan's speckle noise reduction imaging technology uses an advanced multi-scale anisotropic filtering algorithm. This imaging technology is excellent at separating the noise regions from the diagnostic image allowing complex filtering to be performed differently on noise versus true anatomic information thus producing an enhanced image
Multi-beam Technology
Ultrasound systems use beams that are focused electronically to produce high spatial resolution. Signals from the transducer are delayed and added together in the system to produce a focused ultrasound beam. The same signals can be added together with different delays to produce multiple beams. When this is done, the spatial resolution can be improved without reducing the frame rate or the frame rate can be improved without reducing the resolution. As shown below, with dual beamformation the same receive beams are formed with half the transmit beams, thus doubling the frame rate.
