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 Measure function.
2. Select LV Simpson measurement on the touch screen and then select one measurement label
from A4C Dias. , A4C Sys. , A2C Dia s., and A2C Sys. .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 ventricle.
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:
6. Pivot the Point D caliper to a new desired position if necessary.
7. Press < Set> key to complete the measurement.
