5-6 Image Optimization
ExFov
Tap [ExFov] on the touch screen to turn on/off the function.
For linear probes, the ExFOV function displays as trapezoid imaging.
For convex and phase probes, the ExFOV function displays as extending the scan angle.
Impacts
The FOV position/range is available only for the convex and phased probes.
Steer is available only for linear probes.
Line Density
Description
The function determines the quality and information of the image.
Operation
Tap [Line Density] on the touch screen to adjust the parameters.
Levels of line density: UH/H/M/L.
Impacts
The higher the line density is, the higher the resolution becomes.
Dynamic Range
Description
Adjusts contrast resolution of an image, compresses or expands gray display range.
The real-time dynamic range value is displayed on the image parameter area in the
upper left corner of the screen.
Operation
Rotate the knob below [Dynamic Range] to adjust the parameters.
Rotate the knob clockwise to increase the value; rotate the knob counterclockwise to
decrease the value.
The adjusting range of parameter is 30-260 dB.
Impacts
The more the dynamic range, the more specified the information, and the lower the
contrast with more noise.
Smooth
Description
This feature is used to reject the noise and smooth the image.
Operation
Tap [Smooth] to adjust the parameter.
The system provides 6 levels of smooth function. The bigger the value is, the higher the
smooth becomes.
S-iClear
Description
This function is used to increase image profile, so as to distinguish the image boundary.
Operation
Tap [S-iClear] on the touch screen to adjust the parameters.
The system provides 7 levels of iClear effects adjustment,
Off
represents iClear is
disabled, and the bigger the value is the stronger the effect becomes.
Impacts
Larger edge enhance may lead to noise increase.
Persistence
Description
Used to superimpose and average adjacent B images, so as to optimize the image and
remove noises.
