Frequency
2D, M-Mode Rotate to adjust the probe's operating frequency. The selected frequency is
displayed in the Parameter window. For some probes/applications the lowest
frequency settings will be Octave imaging settings.
Push to turn Octave imaging on/off.
CF, Doppler, TVI,
SRI
Enables the adjustment of the transmission frequency to control the sensitivity or
the level of penetration. The selected frequency is displayed in the Parameter
window. Adjusting Frequency may affect Sample Volume and LVR settings.
Frame rate
2D, CF, Doppler, TVI,
TT, SR, SRI, TSI
Adjusts frame rate (FPS). The relative setting of the frame rate is displayed in the
Parameter window. When adjusting frame rate, there is a trade off between spatial
and temporal resolution.
Up/Down
2D, M-Mode, CF Up/Down: enables the 2D image to be flipped 180 degrees.
Left/Right
2D, CF Left/Right: enables a mirror image of the 2D image to be created. The left/right
reference marker V moves to the other side of the image.
Compress
2D, M-Mode Controls the amount of contrast in the 2D image. An index number is displayed on
the control to indicate the relative level of compression.
Doppler Enables control over the contrast of the Doppler spectrum. When compression is
raised, the spectrum image becomes softer and some low level background noise
may appear. Compress is available in both Live and Freeze.
TVI, SRI Controls the amount of color compression. The color bar is adjusted accordingly.
Reject
2D, M-Mode Adjusts the rejection level. When this control is increased, low-level echoes are
rejected and appear darker in the 2D image. An index number is displayed on the
control to indicate the relative level of rejection.
Doppler Enables undesirable background noise to be removed from the Doppler spectrum
resulting in a darker background. Reject is available in both Live and Freeze.
Data Dependent Processing (DDP)
2D Performs a temporal processing which reduces random noise without affecting the
motion of significant tissue structures. An index number is displayed on the control
to indicate the relative DDP level.
