6 Image Acquisition
Operator’s Manual 6 - 13
6.7.1 PW/CW Mode Image Scanning
Perform the following procedure:
1. Select a high-quality image during B mode or B + Color (Power) mode scanning, and adjust to
position the area of interest in the center of the image.
2. Tap [PW]/[CW] to enter PW sampling line adjustment status.
The sampling status will be displayed in the image parameter area in the top-left corner of the
screen.
– Set the position of the sample line by dragging the sampling line; drag the SV gate to
place the SV on the target.
– Adjust the angle and SV size according to the actual situation: drag the PW angle line to
change the angle, pinch on the image area to adjust SV size.
3. Tap [PW]/[CW]/[Update] or double-tap the sampling line to enter PW mode and perform the
examination.
You can also adjust the SV size, angle and depth in real-time scanning.
4. Tap [Image] to open the image menu. Adjust the parameters to optimize the image.
6.7.2 PW/CW Mode Image Parameter
Gain
This function is intended to adjust the gain of spectrum map. The real-time gain value is displayed
in the image parameter area.
SV
To adjust the SV position and size of sampling in PW mode, the real-time value of SV and SVD are
displayed in the image parameter area in the top-left corner of the screen.
CW Focus Position
To adjust the CW mode SVD. The real-time focus position value is displayed in the image
parameter area in the top-left corner of the screen.
Image Quality
Refers to the transmitting frequency in Doppler mode of the probe, the real-time value of which is
displayed in the image parameter area.
Scale
This function is used to adjust the speed range of color flow, which is adjusted through PRF in the
system. The real-time PRF value is displayed in the image parameter area.
To provide a much clearer color flow image.
Use low PRF to observe low-velocity flows, and use high PRF to observe high-velocity flows.
iTouch
To optimize image parameters as per the current tissue characteristics for a better image effect.
Auto Calculation
This function is used to trace the spectrum and calculate the PW mode image parameters. The
results are displayed in the results window.
In real-time scanning, the results displayed are derived from the calculation of the latest cardiac
cycle.
