• Use the Depth control to adjust the range to be imaged.
• Use the Frequency control (move to higher frequencies) or
the Frame rate control (move to lower frame rate) to
increase resolution in image.
• Use the Frequency control (move to lower frequency) to
increase penetration.
• Use the Reject control to reduce noise in the image.
• Use the DDP control to optimize imaging in the blood flow
regions and make a cleaner, less noisy image.
• Use UD Clarity (Cardiac) or UD Speckle reduce
(non-cardiac) to reduce image speckle. Extra care must be
taken to select the optimal Speckle reduction level, as too
much filtering of speckle can mask or obscure desired
image detail.
• Adjust Octave to toggle between Fundamental and
Harmonic mode.
• Press Color maps and select a gray map from the menu on
screen.
• Use HD (High Definition) to smooth out the speckle and
reduce the noise in the image.
• Use ACE (Adaptive Contrast Enhancement) to emphasize
echoes from real structures while reducing noise/haze. This
will result in enhanced signal-to-noise ratio. A sub-selection
of ACE allows the user to adjust how much ACE is applied,
including a setting showing the coherence factor.
• If using a 4D probe:
• Adjust the Quick Rotate control on the Touch panel or
press Angle on the Control panel to rotate the scan
plane to pre-defined angles.
• Adjust the Rotate rotary of the Touch panel to fine tune
the angle adjustment.
A scan plane indicator is displayed showing the angle
position of the scan plane.
WARNING
Always use the minimum power required to obtain acceptable
images in accordance with applicable guidelines and policies.
