• 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.
• 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 predefined 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.
