3. Perform two spline measurements following the Spline method in section 8.1.1.2
Circumference/Area measurement.
4. Then the Stenosis measurement result displays.
8.1.1.6. Elastography Ratio
Elastography Ratio(Eratio) can measure the strain ratio between lesion and normal tissue. There are
Ellipse and Trace methods.
Ellipse Method:
1. Invoke the generic measurement function.
2. Select Eratio-> Eratio Ellipse.
3. Measure the lesion (Displayed as A=XX%) following the Ellipse method in section 8.1.1.2
Circumference/Area measurement.
4. Measure the normal tissue (Displayed as B=XX%) following the Ellipse method in section
8.1.1.2 Circumference/Area measurement.
5. The system automatically calculates the strain ratio between lesion (A) and normal tissue (B). It
is suggest to measure the lesion and normal tissue at the same depth.
Trace Method:
1. Invoke the generic measurement function.
2. Select Eratio-> Eratio Trace.
3. Measure the lesion (Displayed as A=XX%) following the Trace method in section 8.1.1.2
Circumference/Area measurement.
4. Measure the normal tissue (Displayed as B=XX%) following the Trace method in section
8.1.1.2 Circumference/Area measurement.
5. The system automatically calculates the strain ratio between lesion (A) and normal tissue (B). It
is suggest to measure the lesion and normal tissue at the same depth.
