Real Time 4D mode is obtained through continuous volume acquisition and simultaneous
rendering. 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. After freezing, the image size
can be adjusted manually if desired, or play back the Volume Cine.

VCI (Volume Contrast Imaging) is an option.
By setting a small volume sweep angle you scan a limited number of slices with a relatively
high volume rate. The render box is very narrow and so you can visualize the tissue
information of a thick slice. A mixture of surface texture and transparent maximum (or X-ray)
rendering modes (70/30) plus a low setting of surface transparency (20-50) is used. The
resulting image shows the average (integrated) gray values of the tissue contained within the
narrow box. Volume Contrast Imaging [VCI] improves the contrast resolution and the signal /
noise ratio and therefore facilitates the detection of diffuse lesions in organs. The result is an
image with no speckle pattern and a highly improved tissue contrast.
