Volume Mode
11.5 Real Time 4D Acquisition
Principle
Real Time 4D mode is obtained through continuous volume acquisition and parallel calculation of 3D
rendered images. In Real Time 4D mode the volume acquisition box is at the same time the render
box. All information in the volume box is used for the render process. Therefore size and position of
the volume box is important for a good render result.
The size of a calculated 3D image is set automatically in that way that the content of the render box
fits to the chosen display mode area.
After freezing, the 3D image size can be adjusted manually if desired, or play back the 4D cine.
This algorithm ensures that independent from size of the volume box, the entire 3D image will always
be displayed in a proper manner.
Condition for Real Time 4D:
• Software option "Real Time 4D" is installed.
• A Real Time 4D probe is connected and selected.
Operation:
1. Activate Volume mode (hard key)
2. Select [4D Rendering] or [Sect. Planes] Visualization mode from
the menu area.
Note:
Depending on the selected Visualization mode [4D Rendering] or [Sect. Planes], different
menus will be displayed during and after the Real Time 4D acquisition.
3. Select a 4D User Program (e.g., Default).
The preset values are loaded.
4. Select the display format desired.
