Analysis
Analysis consists of viewing previously saved loops and
assigning scores to each cardiac segment, in order to quantify
the function of the muscle, or wall motion.
Depending on the protocol configuration, the analysis stage
can be started automatically after completion of the stress test
or it can be started manually. In this case, the usual procedure
consists of sequentially opening all image groups (if defined)
and perform scoring from image to image.
The quad screen is the standard display for comparing heart
cycles (Figure 5-9). The heart cycle loops in the display are
synchronized to enable comparison. Each loop in the quad
screen can be magnified, using the "Crop Images" function
(see page 591) or the zoom control (see page 120).
Image selection for analysis
Images can be selected manually or from a pre-defined group
in the Protocol screen.
Selection of images from a group
If groups of images have been defined in the protocol template
(see page 231), the user can select a group of images for
analysis and sequentially analyze all images from all groups
from within the analysis screen (see Figure 5-9, page 215).
1. In a stress examination, press
PROTOCOL.
A preview of the acquisitions is displayed.
2. Trackball to a group in the Group list.
The frame of the images belonging to the group are
highlighted.
3. Press
SET to open images in the Analyze screen (see
page 216).
Note: Pressing

Protocol screen) automatically opens the first group of images
in the analysis screen.
