Description
Controls the angle of the color sample volume (Only for
Liner Array Probe).
Adjusts the transmission frequency to control the sensitiv-
ity and the level of penetration. The selected frequency is
displayed in the status window. Adjusting Frequency may
affect Sample Volume and LVRej settings.
Switch to Color Mode.
Adjusts the Frame Rate.
BC SameWidth
Adjusts the
width of 2D Mode is the same as that of Power Mode.
Description
Prioritizes the image with the information about blood
flow of Power Mode.
Improve the sensitivity of the signal in time domain.
Smooths the image by averaging collected horizontal
data. Increasing lateral averaging will reduce noise, but
may also reduce lateral resolution.
Smooths the image by averaging collected radial data.
Increasing radial averaging will reduce noise, but may also
reduce radial resolution.
Displays a menu of color map options. Each color map is
assigning different color hues for different velocities.
Controls the amount of acoustic power applied in all
modes. Acoustic power cannot be set above the amount
permitted by the FDA. The Thermal index (TI) and the
Mechanical index (MI) are displayed on the screen.
Description
Adjusted by the knob below the TGC on the control panel.
When rotated clockwise, increases the overall gain applied
to the received echo signals equally for all depth.
Compensates for depth-related attenuation in an image.
The sliders nearest the operator affect the far field. TGC
amplifies returning signals to compensate for the attenua-
tion caused by tissue at increasing depths.
