Image Optimization 5-5
ExFov
Click [ExFov] on the image menu to turn on/off the function.
For linear probes, the ExFOv function displays as trapezoid imaging.
For convex probes, the ExFOv function displays as extending the scanning
angle.
Impacts
You can get a much larger field of view when selecting a larger FOV, but the
frame rate will decrease.
Line Density
Description
The function determines the quality and information of the image.
Operation
Adjust through the [Line Density] item in the menu;
Levels: UH/ H/ M/ L.
Effects
The higher the line density, the higher the resolution, and the lower the frame
rate.
Dynamic Range
Description
This function is used to adjust the B image resolution to compress or expand
the 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
Adjust through the [Dyn Ra.] item in the menu;
The adjusting range is 30-220 in increments of 5.
Effects
The more the dynamic range, the more specific the information, and the lower
the contrast with more noise.
iClear
Description
This function is used to increase image profile, so as to distinguish the image
boundary.
Operation
Adjust through the [iClear] item in the menu;
The system provides 5 levels of iClear effects adjustment, off represents no
iClear is turned on, and the bigger the value the stronger the effect.
Effects
The bigger the value the clearer the profile of the image.
Persistence
Description
This function is used to superimpose and average adjacent B images, so as to
optimize the image and remove noises.
Operation
Adjust through the [Persistence] item in the menu;
The system provides 8 level of frame average adjustment, the bigger the
value the stronger the effect.
Effects
Persistence can remove image noise to make details to be clearer.
Impacts
Persistence increase may lead to signal missing.
Rotation/ Invert
Description
This function provides a better observation for image display.
