bkSpecto Advanced User Guide (16-01642-01) Imaging Modes 75
Color Box
When elastography mode imaging is turned on, a color box is superimposed on the
B-mode image. The color box outlines the area of the tissue in which information is
available.
You can adjust the position and size of the color box to examine various parts of the
B-mode image. The view must be imaging when you do this.
To move the color box:
•
Drag it with the trackpad.
To resize the color box:
1
Tap the trackpad. The corners of the color box turns white.
2
Drag right or down to increase the box in width and height.
3
Drag left or up to decrease the box in width and height.
Color Map
The color map represents the variants in levels of relative hardness/softness. The
default setting is red = hard, and blue = soft. If you touch and slide the
Map
parameter button, you can choose from a set of different color codes.
Quality Indicator
The quality indicator displays the amount of pressure being placed on the transducer.
If the green indicator is at the top, transducer compression is at the optimum level,
but even if the indicator shows only one square, the image can be useful. A good
image is one that can be reproduced.
Strain Ratio Measurement
Strain ratio measurements can be used to quantify the relative stiffness between the
region of interest (ROI) and the surrounding tissue. To perform a strain ratio
measurement:
1
Tap Measure and select Strain Ratio.
2
Tap inside the ROI and then slide the trackpad to create a measurement circle.
When the circle is the required diameter, tap again to set the measurement circle
on the screen.
3
Repeat the measurement process outside the ROI.
The strain ratio appears in the measurement data to the left of the image.
