IRECTION
5-2-4-2 DICOM (cont'd)
Sending of reports - Additionally all OB/Gyn measurements can be sent to a PC*.
Receiving of these reports is supported by ViewPoint workstation "PIA" only. All other workstations can
be adapted individually.
* Without using structured reporting.
5-2-4-3 VOCAL II - Virtual Organ Computer-aided Analysis
Diagnosis and therapy of cancer is one of the most important issues in medical care.
The VOCAL II - Imaging program allows completely new possibilities in cancer diagnosis, therapy
planning and follow-up therapy control.
VOCAL II offers additional functions:
• Manual or Semi automatic Contour detection of structures (such as tumor lesion, cyst, prostate,
etc.) and subsequent volume calculation.
The accuracy of the process can be visually controlled by the examiner in multi-planar display.
• Construction of a virtual shell around the contour of the lesion. The wall thickness of the shell can
be defined. The shell can be imagined as a layer of tissue around the lesion, where the tumor
vascularization takes place.
• Automatic calculation of the vascularization within the shell by 3D color histogram by comparing the
number of color voxels to the number of grayscale voxels.
5-2-4-4 Advanced VCI
5-2-4-4-1 VCI Omni View - Volume Contrast Imaging (any plane)
More flexibility with Any Plane, VCI plane is freely selectable. Any shape can be drawn.
Volumes from older BT's can be loaded and edited with VCI Omni View without any limitations.

5-2-4-5 STIC "Basic" (Spatio-Temporal Image Correlation)
With this acquisition method the fetal heart or an artery can be visualized in 4D.
It is not a Real Time 4D technique, but a post processed 3D acquisition.
In order to archive a good result, try to adjust the size of the volume box and the sweep angle to be as
small as possible. The longer the acquisition time, the better the spatial resolution will be.
A good STIC, STIC CFM (2D+CFM), STIC PD (2D+PD) or STIC HD (2D+HD-Flow) data set shows a
regular and synchronous pumping of the fetal heart or of an artery.
The user must be sure that there is minimal movement of the participating persons (e.g., mother and
fetus), and that the probe is held absolutely still throughout the acquisition period. Movement will cause
a failure of the acquisition. The acquired images are post processed to calculate a 4D Volume Cine
sequence. Please make sure that the borders of the fetal heart or the artery are smooth and there are
no sudden discontinuities. If the user (trained operator) clearly recognizes a disturbance during the
acquisition period, the acquisition has to be cancelled.
• STIC - Fetal Cardio is only available on RAB & RIC probes in the OB/GYN application.
• STIC - Vascular is only available on the RSP probe in the Peripheral Vascular application.
NOTICE The option "STIC" is only available for Voluson E6 systems.
"STIC" is part of the "Advanced STIC" option for Voluson E8 systems.

EVISION
Volumes can be edited in all other Visualization Modes.
Dual Format is now also possible in Render Mode and Sectional Planes Mode.
VCI slice thickness can be set to zero.
