Q SAVE
(Quick Save)
During real-time
2D
and Color Flow imaging, the
Q SAVE
key
saves loops each time the key is pressed (the number of
loops saved is defined in the system setup; see “Explanation
of Setup Menu Fields” on page 3-4). A loop is defined as,
either:
If using
ECG:
a
single cardiac cycle
If not using
ECG:
a
period of time
In real-time
CW
Doppler,
PW
Doppler, or M-Mode, pressing
Q SAVE
saves a single sweep screen. In Freeze mode,
Q SAVE
saves the frozen image displayed on the screen. It
also saves loops stored in temporary memory by pressing
Q SAVE
while the loop is playing. While images are being
saved, an icon of a camera is displayed in the upper right-
hand corner of the screen. For more information, see “Sav-
ing Image Data” on page 5-5.
FREEZE
The
FREEZE
key suspends active scanning and displays the
last acquired image on the screen as a still frame. Use the
Main knob to scroll backward and forward through the still
images. To save any images as loops, first turn
PLAY LOOP
to display the desired loop or frame, and then press
Q SAVE
or
•
SAVE
. This saves the image currently playing. For more
information about saving, see “Saving Image Data” on page
5-5.
Pressing
FREEZE
a second time unfreezes the image and
returns to real-time scanning. Any unsaved loops are lost
because loops are stored in temporary memory only.
