4D Imaging
4D imaging enables the display of real time 3D anatomical structures.
4D imaging can only be performed by compatible volume probes. 4D imaging adds the dimension of “movement”
to a 3D image by providing continuous, real-time displays of internal organs or fetus. 3D imaging provides single
frame images, while 4D imaging provides continuous, high volume acquisition of 3D images.
The following description uses the fetal imaging as an example, the other imaging options are as the same.
10.1 Acquiring 4D Images
The following description uses 4D imaging performed with the VC6-2 probe as an example.
10.1.1 Entering the Real-Time 4D Imaging
Perform the following steps as follows.
1. Enter the patient information, select the VC6-2 probe and an exam type (such as the obstetric exam used
throughout this chapter) to enter the B mode.
2. Optimize imaging parameters in the B mode.
3. Apply adequate gel on the patient.
4. Acquire a high quality B-mode image.
5. Tap
3D/4D
on the touch screen to enter the inactivated 4D mode by default.
NOTE:
When using a volume probe, you can set the default inactivated 3D or 4D mode. For details, refer to
Section 4.1.4 Dened-Key Settings.
The 2D imaging with a ROI and a sample line is displayed in the inactivated 4D mode, only the data in the ROI
is acquired for 4D imaging.
