MODE.
The function of the assignable keys and the controls assigned 
to the soft menu vary according to the mode in which the 
system is running. A detailed description of each function is 
provided each scanning mode in the following imaging mode 
sections. In combined modes (i.e. combined Color flow and PW 
Doppler), one mode is active (live) while the other is frozen. In 
this case, the assignable keys and rotary knobs control the 
active mode. Switching the active mode will change the key 
and rotary assignments accordingly.

Cineloop operation
When no ECG is 
connected, a cine 
gauge is displayed 
indicating the cur-
rent frame. in the 
cineloop.When the scan mode is frozen, the unit automatically displays 
cineloop boundary markers on either side of the last detected 
heart cycles. The cineloop boundaries can be adjusted using 
the cineloop assignable controls to cover one or more heart 
cycles.

Storing images and cineloops
Images stored on 
the clipboard dur-
ing the scanning 
session are for im-
mediate purposes. 
At the end of the ex-
amination, the data 
should be archived 
in the patient ar-
chiving system (re-
fer to page 269).Images and cine-loops can be stored at any time during the 
scanning session. A thumbnail of the stored image is displayed 
on the clipboard on the scanning screen. An icon will also be 
displayed in the Image Browser and Image Selection screens. 
Protocol based stored images will also be displayed in the 
protocol grid in the Parameters window.
The amount of data stored from 2D live is defined by the 
settings of the current application. The application setting 
controls the number of cycles included (or time span if ECG is 
not active), time span before R-wave...etc (refer to page 397 
and page 400 for further information).
The amount of data stored in images from 2D replay is 
determined by the defined cineloop.
Images can be stored in either DICOM and GE Raw Data 
formats or DICOM format only, depending in the dataflow 
configuration (refer to page 424 for further information).
To store a single image
1. Press FREEZE.
2. Press 
IMG. STORE to store the image digitally. 
The thumbnail of the image is displayed on the clipboard.
See also page 271 for further information.
To store a cineloop
Cineloops may be stored directly or after preview, depending 
on how the system is configured. The procedure for cineloop 
storage is described on page 271.
