Frame Averaging
Imaging Frequency
Description
Averages previous frames of image data
with the current frame. Frame averaging
uses more data points to make up 1
image. This has the effect of presenting a
smoother, softer image.
NOTE: Not available on Cine replay.
In B-Mode, imaging frequency can be
changed to allow more echoes to pass
through.
Benefits
Helps to average out brief, sudden
changes in echo intensity information.
Could help to filter out low intensity noise.
Allows for an increase in echo intensity
without changing gain, TGC or acoustic
output with lower frequencies. Allows for
increased resolution with higher
frequencies.
Values
Frame average values are off, 1, 2, 3, 4, 5
and 6. Frame average values are returned
to the preset value when changing the
following:

Pre-processing function.
Values shown are probe dependent.
Table 5–6 shows the correlation between
the frequency values displayed and the
imaging frequency mode preference
(penetration, normal, resolution, further
penetration, harmonic 1 and harmonic 2).
To set the default image frequency for
B-Mode and M-Mode, refer to Custom
Display pages 2 and 3, respectively.
Further penetration mode is available on
the C358 probe only.
Refer to
5–20 for details on Tissue
Harmonics.
Affects on
Other Controls
Acoustic output, gain and TGC may be
able to be reduced due to increased
penetration.
