• lt can meet the needs of clinical diagnosis and improve the confidence of diagnosis.

• Broadband frequency shift harmonic imaging

• It can effectively reduce noise and improve contrast resolution

• Intelligent speckle noise suppression imaging

  Intelligent speckle noise suppression technology can intelligently identify different tissue information in different spatial dimensions, inhibit the display of     speckle noise edge information, and make the image more exquisite

• Intelligent space composite imaging

  Intelligent spatial composite imaging technology, through spatial multi-angle deflection scanning, updates echo signals received from different angles in real      time, continuously updates fusion imaging, effectively inhibits random noise and clutter signals under the premise of guaranteeing the temporal resolution,     enhances the target organization display, and improves the spatial resolution of the image.High resolution medical LCD.
