5-96 Image Optimization
The adjusting range of basic frequency values can be divided into penetration preferred
(Pen), general mode (Gen), resolution preferred (Res).Please select the frequency
according to the detection depth and current tissue features.
Impacts
Used to optimize the resolution and the penetrability of the image.
Elas Metric
Description
Used to adjust the elastography metric.
Operation
Rotate the knob under [Elas Metric] to adjust the value on the touch screen.
The metric includ
es Young’s modulus E (unit: kPa), and shear modulus G (unit: kPa).
The current elastic modulus or the shear wave velocity (including the unit) appears on
the top of the color bar.
Note: the operation description of the STE in the manual may differ from the real display
of the system because of the configuration variability, please refer to the system the user
purchased.
Scale
Description
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.
Operation
Rotate the knob under [Scale] on the touch screen. The value on the top of the Map
changes as the Scale changes.
The adjusting range: 0 to 29 in increment of 1.
Impacts
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
Description
Used to adjust the opacity feature of the Elasto image.
Operation
Rotate the knob under [Opacity] on the touch screen.The adjusting range: 0 to 5 in
increment of 1.
Map
Description
Used to adjust the color map to achieve the switch between the gray map and the color
map.
Operation
Rotate the knob under the [Map] on the touch screen to select the map.E1 is a gray map;
E2 and E3 are color maps.
ROI Adjustment
Description
This feature is used to adjust the ROI position and scale of the lesion detected in STQ
imaging.
