Rev 1.1 VisualSonics Vevo 2100 Imaging System Operator Manual 213
Chapter 34: Analyzing B-Mode images
When the Average option is selected, the graph displays a
single smooth loop.
When the Average option is cleared, the graph plots the cardiac
cycle.
Volume command
Click this command to toggle the horizontal dimension between Volume and the
basic dimension of the loops. For measurements made in M-Mode the dimension
is Diameter in millimeters. For measurements made in B-Mode, the dimension is
Area in square millimeters.
Export command
Click this command to export the data as one of three file formats:
CSV file. Can be imported into a spreadsheet or database.
BMP file. Exports the graph data as a bitmap image.
TIFF file. Exports the graph data as a vector based image.
Strain rate step 1: Adding the LV wall trace
You measure strain rate using the system's VevoStrain™ application. Included
within the Vevo 2100 Imaging System, this tool produces velocity strain and time-
to-peak analyses on myocardial wall images.
f To create the LV wall trace:
1. From the Study Browser, select the B-Mode cine loop you want to analyze
and then click Vevo Strain.
