Enter 3D Mode
1. Connect 3D transducer (C8-33D or E9-33D) to MTP. System will calibrate and
self-test transducer motor.
2. Acquire and optimize 2D/B-Mode image.
3. Press Mode key you programmed for 3D. You are now in 3D Setup mode.
Enter 4D Mode
1. Select Real-Time (4D) using Static/Real-Time softkey (Figure 7-23). You are
now in 4D Setup mode.
2. Adjust image and position ROI.
3. If desired, maximize volumes per second (VPS):
a. Select FAST using Quality softkey.
b. Choose a fundamental Frequency, e.g., 8.0 MHZ/6.0 MHZ, using
Frequency button.
c. Reduce elevation angle to 45 degrees using Angle softkey.
4. Press Freeze or Start/Stop softkey to initiate volume acquisition (transducer
lens will start sweeping back and forth and image will be in real-time).
5. Press Freeze to stop 4D imaging. Press Freeze again to resume 4D imaging.
6. To return to the ROI, press Mode key you programmed for 3D.
7. To return to 3D (mode, select Static using Static/Real-Time softkey.
EXAMPLE: Fetal Face Surface Rendering
1. Acquire and optimize a B-Mode/2D image of the fetal facial profile in a
mid-sagittal plane, face up.
NOTE: A good B-Mode/2D image is important for a high-quality 3D/4D image.
2. Try to scan showing fluid in front of the fetal face.
3. Press Mode key you programmed for 3D (above).
4. The system enters the 3D Setup state for 3D imaging. The 3D status field
displays on the right-side of the imaging window.
