In real-time scanning, the results displayed are derived from the calculation of
latest cardiac cycle;
In the freeze and cine status, the results displayed are calculated from the
current selected area.
To set the display format of PW mode images with B mode images.
Click the [Display format] item on the image menu to adjust.
Options: V2:1, V1:2, V1:1, Full.
Refers to the area where the velocity is zero in the spectrum.
Click the [Baseline] item on the image menu to adjust.
Changes the flow-velocity range to optimize the image.
This function is used to adjust the angle between Doppler vector and flow to
make the velocity more accurate.
The real-time adjusting angle value is displayed on the right part of the
spectrum map.
Click the <Angle> item on the image menu to adjust.
The adjustable angle range is -89~89°, in increments of 1°.
To adjust the angle faster, in increments of 60°. The real-time value is
displayed on the right part of the spectrum map.
Click the [Quick Angle] item on the image menu.
There are 3 angles for quick adjustment: -60°, 0° and 60°.
The dynamic range conveys the information which is being transformed from
echo intensity to grayscale.
Adjust through the [Dynamic Range] item on the image menu.
The adjusting range is 24-72dB in increments of 2dB.
The more the dynamic range, the more specific the information and the lower
the contrast with more noise.
