8.2.4.1. Simpson’s Method of Disks (MOD)
Simpson’s MOD is a method used to calculate LV diastolic and systolic volumes and ejection fraction.
Simpson’s MOD is available in the Cardiac presets.
To use the Simpson’s MOD measurement:
1. Invoke the B-mode application measurement function.
2. Select a measurement which could be done by Simpson’s method of disks. A single caliper will be
displayed on the image field.
3. Move the caliper and press <Set> key to position the start point A at one end of left ventricular
long axis.
4. Draw the trace along the endocardium of the left ventricular.
5. Press <Set> key to fix the end point B and complete the trace. A new caliper positions
automatically at the apex (Point D) of the trace, connecting the Point C (Midpoint of point A and B).
This distance between point C and D is the longest detected by the system, as shown below:
