Echo Boost
This function can improve contrast and decrease noise, so that a much clearer boundary can be
seen.
Patient Temperature
If the current active probe is TEE probe, the parameter will display under the B mode menu. You
can enter the patient temperature by this function.
WARNING
If the patient temperature is above 37°C (98.6 °F) and the [Patient
Temperature] setting is below the actual reading, the system could
overestimate the temperature of TEE transducer’s distal tip. This could
trigger the Auto-Cool feature. If the patient temperature reaches or is near
37 °C (98.6 °F) and the [Patient Temperature] setting is above the actual
reading, the system could underestimate the temperature of the TEE
transducer's distal tip. The patient is exposed to excessive temperatures.
6.2 Color Mode
The Color mode is used to detect color flow information, and the color is designed to judge the
direction and speed of blood flow.
Generally, the color above the color bar indicates the flow towards the probe, while the color below
the color bar indicates the flow away from the probe. The brighter the color, the faster the flow
speed, while the darker the color, the slower the flow speed.
TIP:
In Color Mode, acoustic power is synchronous with that of B Mode. Adjustment of the depth or
zoom to the B Mode image will lead to corresponding changes in Color Mode image.
6.2.1 Color Mode Image Scanning
Perform the following procedure:
1. Select a high-quality image during B mode scanning, and adjust to position the area of interest
in the center of the B mode image.
2. Tap [Color] on the right side of the operating panel to enter Color mode.
3. Change the position and size of the Region of Interest (ROI).
– Tap the corner of the ROI and drag to change the size.
– Tap inside the ROI box and drag to change the position.
4. Tap [Image] to open the image menu. Adjust the parameters to optimize the image.
6.2.2 Color Mode Image Parameters
Color Gain
Refers to the overall sensitivity to flow signals. The real-time gain value is displayed in the image
parameter area.
Increasing the gain will increase the flow signal presented as well as noise, while the signals may be
missing when the gain is adjusted too low.
