Chapter 36: Analyzing M-Mode images
If the graph displays a single loop, the system plots a red dot
on the curve at the End Diastolic point.
If the graph displays multiple loops, the system plots a best-fit line
through the End Diastolic points.
Average check box
Check this box to display a loop that represents a virtual or averaged cardiac cycle, calculated
from the aggregate cycles defined by each LV wall trace. Clear the check box to display all
cardiac cycle instances. This check box is selected by default.
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.
