S2/S2BW
Digital Color Doppler Ultrasound System
Operation:
GSC
• Press for B-mode menu, use to select GSC;.
• Twist knob to select differenct GSC .
6.2.9 Persist
Persist is an image processing method, it averages each frame to reduce irrelevant noises. Set a lower Persist
value, you can have better real-timeness of image, but also may cause more noise. A higher Persist value
reduces the noise, improve the smoothnss of image but also reduces real-timeness of the image.
Operation:
Persist
• Press for B-mode menu, use to select Persist;.
•
Twist knob clockwisely to increase the value of Persist, and counterclockwisely to reduce the
value of Persist.

nis the function to optimize the ultrasound image. It can reduce speckle noise, enhance contrast
resolution and enhance the display of tissue boundaries.
Operation:
µScan
• Press for B-mode menu, use to select µScan;.
• Twist knob to adjust µScan.
6.2.11 Compound Imaging
In B-mode scanning, sometimes the beam is not vertical to the surface of transducer but has a certain angle.
The final mage is formed by many images of different scanning angles and through image process. The
advantage is to have a better tissue differentiation and enhance the contrast resolution to have a clear edge of
orgain. For a better recognition, the wall of vascular and tissue phrase will be marked specifically.Compound
Imaging can suppress the ultrasound side lobe to enhance the spatial resolution of system and signal-to-noise
ratio to have a better image.
