4.7 Parameter adjustment about PW
mode

PW mode (spectral Doppler mode) is used to provide the information of blood flow direction and
velocity. The transverse axis of the spectrum pattern represents the time and the longitudinal axis
indicates the Doppler frequency shift.

PW mode has the function of distance gating, which can show the velocity, direction and nature of
local blood flow at a certain depth.

CAREFUL

：

The timing of PW mode is not consistent with that of B/C mode, so
it is impossible to move the probe to change the position of
measurement when entering PW mode.

4.7.1 PW mode image parameter

During PW mode image scanning, the image parameter area on the left side of the screen provides
real-time parameter information, which allows you to adjust the following parameters:

Gain, depth

SoftKey adjustment

Speed, baseline, deflection, quick correction angle, flip, SV, wall

filter, frequency, dynamic range, volume, recording range,

pseudo-color map, sound power, time mark, automatic

calculation,automatic calculation parameters

4.7.2 PW mode image optimization

Frequency

Resume

Switching the probe frequency in Doppler mode, the frequency value is displayed
in the image parameter area on the left side of the screen in real time.

Effect

The higher the frequency, the higher the resolution and sensitivity, but the lower the
penetration force.

Trace Area

Resume

Change the Trace Area between Above, Below and All.
