NOTE:
The value of wall lter is also changed when adjusting PRF.
■ High Pulse Repetition Frequency
Once HPRF is enabled, besides the original sample volume gate, one or more sample volume gates appear at
shallower positions on the 2D image. The unnecessary low frequency signal or the disturbances made by non-ow
movements, such as breath, heart beat or sweeps of the probe will be ltered.
To enable the High Pulse Repetition Frequency:
Tap the right part of
PRF
to increase the value continuously, HPRF is automatically enabled when a certain value
is reached.
NOTE:
The linear probes are not available for HPRF.
■ Baseline
Baseline represents the position of zero velocity or frequency. The velocity range in one direction can be increased
or decreased by adjusting the baseline.
Baseline is used to unwraps the alias during color ow imaging, and display higher velocities without reversal of
colors.
To adjust the baseline:
●
Tap the left part of
Baseline
to move the baseline towards the positive direction, and the velocity range in the
color map varies with the adjustment.
●
Tap the right part of
Baseline
to move the baseline towards the negative direction, and the velocity range in
the color map varies with the adjustment.
■ Wall Filter
Wall lter is used to lter the low frequency noise from tissues, such as the vascular wall.
To adjust the wall lter:
●
Tap the left part of
WF
on the touch screen to decrease the value.
●
Tap the right part of
WF
on the touch screen to increase the value.
■ Frequency
The probe is capable of generating a broadband signal with a certain frequency and bandwidth. The frequency
optimizes the edges when scanning deeper locations with Doppler imaging.
To adjust the frequency:
●
Tap the left part of
Frequency
on the touch screen to decrease the value.
●
Tap the right part of
Frequency
on the touch screen to increase the value.
■ Sweep Speed
Sweep speed is used to set the sweep speed of the Doppler trace. The refresh speeds of the time scale and the
frequency scale vary with the sweep speed.
To adjust the sweep speed:
●
Tap the left part of
Speed
to decrease the value.
●
Tap the right part of
Speed
to increase the value.
