Figure 6-20 Spectral Doppler Mode Imaging Parameters Menu
To optimize an image by using controls in the following instructions:
●
Tap the left or right part of an item to adjust the parameter, the value displays at the
bottom of the item. You can tap on the touch screen to turn the current menu to
the previous or the next page if it displays over one page.
●
Or, rotate the knob on the control panel that is directly below the selected item to
adjust the value.
NOTE:
You can adjust all parameters in the real time PW/CW mode, but can only adjust
Baseline , Chroma and Display Format in the frozen PW/CW mode.
Gain
PW/CW gain is used to adjust the gain of the spectrum map. Increasing the gain will
brighten the image, allowing you to see more received signals with less noise.
To adjust the gain:
●
Rotate the PW or CW knob on the control panel clockwise to increase the value.
●
Rotate the PW or CW knob on the control panel anticlockwise to decrease the value.
Pulse Repetition Frequency
Pulse repetition frequency is used to adjust the velocity scale, filter the unnecessary low
frequency signal or the disturbance made by non-flow movements, such as breath, heart
beat or sweeps of the probe.
