4 Examination Fundamentals
4 - 18 Instructions for Use
Priority Mode
A mode must have visibility or priority over any other activated modes for you to adjust the
controls or make menu selections for that mode. During combined mode imaging, more than
one mode may be activated at any given time, but only one mode is the priority mode. When a
mode is activated, the previous mode with priority remains activated, but it is no longer the
priority mode.
To change the priority mode during combined mode imaging:
Activate the required mode.
● Press the control for the required mode. Or, select the tab for the required mode on
the touch screen.
○ For systems without a touch screen, press PRIORITY.
The image menu and the trackball status area indicate the current priority mode.
2D-Mode Overview
2D-mode is the default imaging mode for the ultrasound system. It indicates brightness or
two-dimensional (2D) gray scale imaging. You can display dual 2D-mode images, select
transducer-dependent image formats, and adjust imaging parameters for the active image.
M-Mode Overview
M-mode displays a 2D image and an M-mode sweep. The cursor represents the acoustic line
along which the M-mode information is gathered.
During cardiac exams, use Anatomical M-mode to view an M-mode sweep based on the
patient's anatomy and independent of transducer orientation. You can rotate and reposition the
anatomic M-mode cursor to align with the patient's anatomy.
