Image Optimization 5-7
FOV (Field
of View)
1. To change the scan range, click [FOV] on the image menu to enter the
FOV range and FOV position adjustment status.
2. Press <Set> to switch between adjusting FOV position and FOV range by
the icon hint information below the image:
z
indicates FOV position adjusting status, and
indicates
FOV range adjusting status.
3. Rotate the trackball to adjust FOV position or the FOV range.
When the scan range is adjusted to the widest, the FOV position can not be
changed.
You can get a much larger field of view when selecting a larger FOV, but the
frame rate will decrease.
Steer
This function is to steer the beam transmitted by the probe.
Adjust it by pressing <Steer> key on the control panel or click [Steer] on the
image menu.
Steer angle range varies by probe.
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
Steer is available only for linear probes.
Line Density
Description
The function determines the quality and information of the image.
Operation
Adjust through the [Line Density] item on 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 [Dynamic Range] item on 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 on the menu;
The system provides 4 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.
