8.2.2 Image Parameters
E Quality
Used to select the transmitting frequency of the current probe, the real-time value of which is
displayed in the image parameter area in the upper left side of the screen.
Rotate the knob under [E Quality] on the touch screen to select the different THI frequency value.
Please select the frequency according to the detection depth and current tissue features.
Elas Metric
Used to adjust the elastography metric.
Rotate the knob under [Elas. Metric] to adjust the value on the touch screen.
The metric includes Young’s modulus E (unit: kPa), shear modulus G (unit: kPa), and shear wave
velocity Cs (unit: m/s).
The current elastic modulus or the shear wave velocity (including the unit) appears on the top of the
color bar.
Scale
Used to change the maximum scale to make the map related to the color at the top of the bar.
Optimize the elasto modulus, or mirror the elasto wave velocity to the map.
Rotate the knob under [Scale] on the touch screen. The value on the top of the Map changes as the
Scale changes.
Parts which exceed maximum elasto modulus or shear wave velocity will be mapped onto the color
on top of the color bar at top-left part of the image. Thus if the color in the ROI is mainly the color
on top of the color bar, you need to increase the metric range.
Opacity
Used to adjust the opacity feature of the Elasto image.
Tap [Opacity] on the touch screen. The adjusting range: 0 to 5 in increment of 1.
Map
Used to adjust the color map to achieve the switch between the gray map and the color map.
Tap [Map] on the touch screen to select the map.
ROI Adjustment
This feature is used to adjust the ROI position and scale of the lesion detected in STQ imaging.
Rotate the knob under the [Fixed ROI] item on the touch screen to adjust the fixed size of the ROI,
or press the <Set> key and roll the trackball to adjust the ROI position and scale. The ROI includes
lesions and surrounding normal tissues.
The “+” sign indicates the ROI center, and the Depth value of the ROI center is displayed at the
bottom right corner of the screen.
Display Format
Used to adjust the display format of ultrasound image and the Elasto image, and return to the
previous state.
Tap each soft key on the touch screen to complete the adjustment.
More accurate result is obtained based on the actual situation.
HQElasto
Turn on high-quality scanning mode to optimize penetration.
