Cannot see cardiac
image.
Check the transducer position, and adjust if necessary.
Gain.
Frequency Fusion. Otherwise, change to a lower
frequency transducer.
Touch Harmonic Fusion and choose setting 1.
Increase the frame rate by decreasing the width with
and the trackball. If necessary, use Zoom.
Postproc to select a higher contrast curve.
Touch Colorize to improve contrast resolution.
Power.
Use Harmonic Fusion to reduce clutter and delineate
tissue borders.
Cannot see lateral
walls with sector
transducers.
Adjust the LGC sliders that affect the wall area. Then
adjust the sliders that affect either side of the wall area,
to keep the LGC profile smooth instead of peaked.
Use Harmonic Fusion to reduce clutter and delineate
tissue borders.
Vessel walls are
unclear.
With a linear transducer, adjust Steering to make the
beam perpendicular to the walls.
Reposition the transducer.
Adjust TGCs, Gain, and Compress.
Use soft echo enhancement to emphasize certain
pathologic or physiologic conditions.
In soft echo
enhancement mode,
external radio
frequency
interference (RFI)
affects the image.
Select Soft Echo Enhance A or Soft Echo Enhance
B, instead of Soft Echo Enhance C.
