1. Select a 4D probe, and an application.
2. Enter 4D either by pressing the 4D button on the Control
panel or by selecting a 4D acquisition preset on the Touch
panel: Medium (medium size sector with top-down view),
Large (large sector more suited for acquisition of the
complete LV), or Bird's view on page 2 (small sector seen
from the side).
4D acquisition may also be done in Multi-Slice mode
('Multi-Slice acquisition' on page 6-10) and 4D Zoom
prepare mode ('4D Zoom prepare acquisition' on
page 6-13).
The volume acquisition is started.
3. The following parameters may be adjusted during
acquisition:
• Volume size: adjust the volume size. An increase of the
volume size will reduce the volume rate.
• Volume shape: adjust the ratio between the elevation
and azimuth widths. Changing the volume shape from
default will increase the volume rate.
• Frame rate: adjust the frame rate. There is a trade-off
between the frame rate and the image quality.
• Elevation tilt: tilt the volume in the elevation plane and
change the viewing direction accordingly.
• Other parameters: Frequency and Octave.
• Angle: display different rendering views.
• Layout: display different layout alternatives.
4. Optimize the image quality as necessary (2D Gain, 4D Gain,
Volume Optimize and UD Clarity).
• If desired, select a Color map to colorize the volume
rendering. The Depth color maps use a combination of
colors to improve depth perception.
Press Red or Color Laser lines on the Touch panel
(page 2) to visualize the 2D image locations in the volume
rendering. The 2D image locations are shown as overlaying
red or color coded lines following the surface in the volume
rendering. The color of the laser lines corresponds to the
color coding used for the 2D images.
5. Press Store to store the acquisition.
