Task
Real Time 4D - continuous volume acquisition and parallel calculation of 3D rendered images
Volume Contrast Imaging - improves the contrast resolution and the signal / noise ratio and
therefore facilitates finding of diffuse lesions in organs
Single View (any plane) - improves the contrast resolution and the signal / noise ratio and
therefore facilitates finding of diffuse lesions in organs.
Volumes can be edited in all other Visualization Modes.
Real Time 4D Biopsy - continuous volume acquisition + parallel calculation of 3D rendered images
Changes the line density against the acquisition speed (low, mid1, mid2, high1, high2).
To select the Volume Sweep Angle.
- Quarter size display of Sectional planes without 3D image or
- Quarter size display of Sectional planes + rendered 3D image
(Note: The display depends on selected Acquisition- and Visualization Mode!)
Dual size display of Sectional Planes + rendered 3D image.
(Note: The display depends on selected Acquisition- and Visualization Mode!
This format is not possible for Static 3D Acquisition)
- Full size display of a the reference image or
- Full size display of the rendered 3D image.
(Note: The display depends on selected Acquisition- and Visualization Mode!)
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.
Press the FREEZE key resp. the right trackball key to start the Volume acquisition.
After resp. during Volume Mode Acquisition:
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).
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).
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).
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.
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.
