6 Image Acquisition
Operator’s Manual 6 - 5
You should perform exams according to actual situation and follow the ALARA Principle.
Scan range and FOV position
More information can be obtained without moving the probe or changing the sampling position.
• The FOV position/range is available only for the convex and phased probes.
• When the scan range is adjusted to the widest, the FOV position cannot be changed.
B Steer
To steer the beam the probe transmits.
Steer is available only for linear probes.
ExFov
For linear probes, the ExFOV function displays as trapezoid imaging.
For convex and phase probes, the ExFOV function displays as extending the scan angle.
Line Density
The function determines the quality and information of the image.
Dynamic Range (Dyn Ra.)
Adjusts contrast resolution of an image, compresses or expands gray display range.
Smooth
This feature is used to reject the noise and smooth the image.
iClear
The function is used to enhance the image profile so as to distinguish the image boundary for
optimization.
iClear
+
This function is the advanced version of iClear. It can better enhance image quality, reject noise,
and provide better contrast resolution.
If iClear
+
is configured, iClear will be replaced by iClear
+
.
Persistence
Used to superimpose and average adjacent B images, so as to optimize the image and remove
noises.
Rotation/Flip
This function provides a better observation for image display.
The “M” mark indicates the orientation of the image; the M mark is located on the top of the
imaging area by default.
