Description
Inverts the color scheme for positive and negative veloci-
ties. Invert is available in Live and Freeze.
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.
Adjusting the depth will influence diagram frame rate and
resolution. Decreasing the depth may allow for higher
frame rate and lower resolution. Increasing the depth will
increase image resolution and decrease frame rate.
Enables multiple image display windows in which two or
four images can be viewed simultaneously.
Display more Main menu controls: Simultaneous, TVI
(phased array probe), TDI (phased array probe), EI (linear
array probe and convex array probe), SRI (phased array
probe).
While in 2D mode, press CFM key on the control panel.
