Running Continuous capture
1. Do all your pre-stress acquisitions in the Cardiac 
application.
The application Ex-
ercise should be 
used in order to get 
maximum continu-
ous capture buffer.2. Press PROTOCOL to enter the stress echo mode.
The Protocol screen is displayed (see Figure 4-1, 
page 149).
3. Press Te m p l a t e.
The template list is displayed.
4. Select the template Exercise.
The Exercise proto-
col template is auto-
matically selected 
when the applica-
tion Exercise is ac-
tive.5. Press Begin/Cont.
6. Acquire the resting loops in all four views.
7. Once the fourth loop is acquired the system enter into a 
waiting mode where Continuous Capture is in pause state 
awaiting the patient to exercise.
8. When the patient is back on the bed, press 
IMAGE STORE or 
2D FREEZE. The Continuous capture acquisition is started.
9. Acquire all your views. 
The memory buffer gauge increases (Figure 4-5). When 
memory filling exceeds 90%, the percent number turns 
red.
10. Press 
FREEZE to finish.
11. Press the 
SELECT CYCLE assignable.
The Continuous capture selection screen is displayed (see 
Figure 4-6, page 160).
If the buffer is filled up the system will automatically display 
the Continuous capture selection screen.
Refer to the next section if additional image acquisition is 
necessary after the buffer is filled up.
12. Assign the cineloops to the four views (see page 160).
A dialogue window is displayed asking whether the entire 
Continuous capture acquisition should be saved or not.
Saving the entire 
loop takes 5 to 10 
seconds on Loca-
lArch-IntHD and 
several minutes on 
LocalArch-MOD.13. Press Delete to discard the loop
or
Press Store all to keep the entire loop.
14. Perform Analysis and scoring (see page 163).

Continuous capture with additional image acquisition
If the buffer is filled up before all the image acquisitions are 
done, additional loops can be stored in the clipboard before 
doing image assignment to the views:
1. Perform Continuous capture as described above (steps 1 to 
10).
2. • If the buffer is not filled up: press More and Protocol 
Pause. Live scanning is activated.
• If the buffer is filled up: press Select later in the 
Continuous capture selection screen. Live scanning is 
activated.
3. Perform the additional acquisition (e.g. CFM, Doppler). 
Images will be stored outside the protocol.
4. In order to resume the stress echo exam and assign loops 
for the views from the Continuous capture buffer, press 
PROTOCOL.
5. Press on the Continuous capture icon on the lower left 
corner of the Protocol screen.
The Continuous capture selection screen is displayed.
6. Assign the cineloops to the views (see page 160).
A dialogue window is displayed asking whether the entire 
Continuous capture acquisition should be saved or not.
7. Press Delete to discard the loop
OR
Press Store all to keep the entire loop.
The normal procedure is to discard the loop. The loop is 
very big and will take a lot of disk space.
8. Perform Analysis and scoring (see page 163).
Postponed image assignment
The assignment of the cineloops to the views can be done on a 
later stage on a stored Continuous capture acquisition.
1. Perform Continuous capture as described in ’Running 
Continuous capture’ on page 157 (steps 1 to 11).
The continuous 
capture loop is very 
big, and ending the 
exam may take sev-
eral minutes if stor-
ing through a slow 
network or storing 
to MOD.2. Press Store all.
The entire Continuous capture acquisition is stored. The 
examination can be ended and the image assignment, 
analysis and scoring can be done on a later stage.
3. Re-open the examination if necessary.
4. Press 
PROTOCOL.

1. Press 
RESTART CAPTURE.
The recording in memory is deleted and the Continuous 
capture is started again.
Resume Continuous capture
1. Press 
CONTINUE CAPTURE.
Resumes Continuous capture recording (only if the 
Continuous capture buffer is not full).

Assigning and storing the loops
The cineloops captured in the buffer are assigned to the stress 
protocol views and stored from the Continuous capture 
selection screen (see Figure 4-6).

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 4-9). The heart cycle loops in the display are 
synchronized to enable comparison. Each loop in the quad 
screen can be magnified, using the zoom control (see 
page 70).
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 183), 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 4-9, page 165).
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 
SELECT to open images in the Analyze screen (see 
page 165).
