Description
Protocol
(Soft Win-
dow Knob)
Provides a list of the active stress stages, such as Rest or
Impost, and active views, such as
LAX
(long axis).
FREEZE
Saves several loops in temporary scrolling memory. The
number of loops saved depends on the patient’s heart rate
and the length of time since the last system parameter
change. The loop counter in the upper right portion of the
screen displays the number of loops in the temporary mem-
ory.
Turn the
PLAY LOOP
knob to display individual loops. Label
the loop and then press
•SAVE
or
Q SAVE
to save the loop to
the hard drive.
Q SAVE
(Quick Save)
Saves a cardiac cycle and at the same time lets you label the
loop.
Q SAVE
also automatically advances the view label to
the next view in the sequence.
•SAVE
(Save All)
Turns image saving
ON
and
OFF
as in non-stress exams.
During Impost, when
•SAVE
is activated:
Make sure that the camera icon appears when
•SAVE
is
pressed—the icon confirms that the study is being saved.
The system captures images for 2 consecutive minutes or
until the
•SAVE
key is pressed again.
ROI
(Region of
Interest)
Defines the portion of the sector image that will be played
back in quad-screen format. The
ROI
control is located on
the Tools menu.
The region of interest box may be repositioned after a loop
has been saved by playing the loop back in full-screen for-
mat and clicking the [
ROI
] button.
