Chapter 45: Acquiring Power Doppler Mode images
Control panel controls for Power Doppler Mode
When you are acquiring Power Doppler Mode image data, these are the controls
you use to optimize the image you see on the screen.
Frequency
Adjusts the transmit frequency of the transducer between the higher and lower
frequency levels that are supported by the specific transducer. When you increase the
frequency you can improve detail at the focus depth but the system tends to lose detail at
deeper tissues.
Push forward to increase the frequency. Pull back to decrease the frequency.
Display Map
Cycles you through a predefined set of optimization maps that you can apply either
while you are acquiring or reviewing image data.
Push up or pull down to cycle through the available maps for the active imaging mode.
