Step Task Expected Results
4D Biopsy Real Time 4D Biopsy - continuous volume acqui parallel calculation of 3D
rendered images
2 Quality Changes the line density against the acquisition speed (low, mid1, mid2, high1, high2).
3 Vol.Angle To select the Volume Sweep Angle.
4 Screen Format
- Quarter size display of Sectional planes
- Quarter size display of Sectional rendered 3D image
Note: The display depends on selected Acquisition- and Visualization Mode!
5 Dual size display of Sectional rendered 3D image
Note: The display depends on selected Acquisition- and Visualization Mode!
Note: This format is not possible for Static 3D Acquisition.
6 - Full size display of a reference image or
- Full size display of the rendered 3D image
Note: The display depends on selected Acquisition- and Visualization Mode!
7 Volume Box Position and Volume
Box Size Adjust the Volume Box (ROI) Position resp. Size with the Trackball in the 2D Single
image. The upper trackball key to change the Trackball function from Box Position to
Box Size.
8 Start Acquisition Press the Freeze key resp. the right trackball key to start the Volume acquisition.
9 VISUALIZATION: After resp. during Volume Mode Acquisition:
Render
After the 3D acquisition the system switches automatically to the read menu. The
selected format will be present on the monitor (e.g., 3D ROI Mode: sectional planes A,
B, C + rendered 3D image).
Sectional Planes After the 3D Sectional Planes acquisition the system switches automatically to the read
menu. The selected format will be present on the monitor (e.g., A,B,C - Sectional Plane
mode).
TUI
This method of visualization is consistent with the way other medical systems such as
CT or MRI, present the data to the user (slices through the data set, which are parallel
to each other).
Volume Analysis
The basic idea behind “VOCAL” is the combination of 3D ultrasound tissue (presented
as voxels) and the geometric information of surfaces in a 3D data set. After definition of
contour in 3D space (semi-automatically, manually or spherical) a wide range of
functionality is given.
SonoVCAD Heart
Technology that automatically generates a number of views of the fetal heart. At this
time it can help to find the right and left outflow tract of the heart and the fetal stomach.
SonoVCAD labor Allows to measure fetal progression during the second stage of labor – fetal head
progression, rotation and direction. Visual evidence and objective data of the labor
process are provided.
SonoAVC General
This Feature can automatically detect low echogenic objects (e.g., follicles) in a volume
of an organ (e.g., ovary) and analyze their shape and volume.
Niche Parts of the orthogonal sections A, B and C are compiled to a 3D-section aspect. The
name “Niche” has been chosen because the aspect shows a quasi spatial cut into the
reference image.
