Image Optimization 5-95
Operation Rotate the knob under [E Quality] on the touch screen to select the different THI
frequency value.
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
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
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 Tap [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 Tap [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.
