5.4.8. Additional Control Functions
The DUS 60 also provides the following additional control functions, which are available through
status menus.
Control function Description
Scan Angle (sector
angle/ scan width)
Adjusts the sector angle for curve probes, and the scan width for linear probes,
providing a larger field of view in the far field.
Scan Mode
Selects the scan mode, High density or High FPS (frame rate, in frames per
second)
Dynamic Range Controls the overall contrast resolution of B mode and M mode images.
Edge Enhance
Improves the contour enhancement of the image for distinguishing the edges of
a structure in B mode.
Smooth Adjusts the smooth level.
Frame Persist
Selects the number of frames for frame averaging
to present a smoother, softer
image.
Line Persist Adjusts the line persist level.
Line Average Adjusts the line average level.
AGC Adjusts auto gain control.
Rejection Adjusts the rejection level.
Speckle Reduction Set image speckle reduction attribute.
ATO Set the degree of auto tissue optimization
Gray Map Selects the post-processing gray curve map.
B/W Invert Set the color to black or white.
90° Rotate Rotate the image by 90 degrees (in B mode).
γ Correction Adjusts γ correction.
Sweep Speed Adjusts the scrolling speed level of the M mode and PW mode sweep.
Steer Adjust the sample line position, linear probe only. (0~7)
Filter Adjust the filter wave. (0~3)

These functions can be set using the Set and the Back keys.
5.5. Menu
Menus are displayed on the right of the screen. Only one menu can be activated at a time. The
types are shown as follows:
System status menu
In B mode or B/M mode, the system status menu provides information about the current imaging
mode. In 2B and 4B modes, it indicates the status and parameters of the active image. In M mode,
it indicates the status and parameters of M sweep. In the PW mode, it indicates the status and
parameters of Doppler wave and 2D image. The following are the system status menus of B
mode, B/M mode, M mode, and PW mode respectively.
