Cardiac region measurement

The Cardiac Region measurement traces a region of interest in a Contrast Mode

frame, consisting of two separate traces. The system then measures the difference

in area between the outer trace and the inner trace.

f To place a single cardiac region measurement:

1. Click the cardiac region button .

2. Click along the boundary of the outer wall of the myocardium to add caliper

points.

3. After you add three caliper points, the system creates a simple contour that

connects the points. You can add caliper points by clicking anywhere along

the contour. You don't need to add these points in a particular direction, the

way you should when you add the first three points.

4. Right-click to complete the outer wall contour.
