Operation:
In the B scan, the long line lets you adjust the sample line position, the two parallel lines (that
look like =) let you adjust the sample volume (SV) size and depth, and the line that crosses them
lets you adjust the correction angle (PW angle).
Figure 5-5 Example PW Scan
In PW mode, you can choose scanning in B mode or PW mode by pressing
Update
. When you
are scanning in non-simultaneous mode either the B or the time series window receives data. This
lets you independently change the PW PRF. When scanning in simultaneous mode, both the 2D
and the time series window receive data. This feature lets you define which method is used, based
on the exam type.
The sample volume indicator allows you to start a scan in a B scan mode, set the sample volume,
and switch to Doppler mode. The sample volume locks in position.
