DICOM

Voluson® 730Pro / 730ProV software package providing following DICOM functionality:
• Storage Service Class
• Print Management Service Class
• Structured Reporting Service Class
• Storage Commit Service Class
• Modality Performed Procedure Step Service Class
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.
5-2-5-3 XBeam CRI - CrossBeam Compound Resolution Imaging*
In this special B-mode, beams are transmitted not only perpendicularly to the acoustic window, but also
in oblique directions. Between three and nine beams are correlated to form one image line.
The advantages of CrossBeam Compound Resolution Imaging are enhanced contrast resolution with
better tissue differentiation and clear organ borders. Also vessel walls and tissue layers are emphasized
for easier recognition.

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.

Real Time 4D Biopsy*

For minimal invasive procedures like biopsies, ultrasound is a widely used method to visualize and
guide the needle during puncture. The advantage in comparison with other imaging methods is the real-
time display, quick availability and easy access to any desired region of the patient. The 4D biopsy
allows for real time control of the biopsy needle in 3D multi-planar display during the puncture. The user
is able to see the region of interest in three perpendicular planes (longitudinal, transversal and frontal
section) and can guide the biopsy needle accurately into the centre of the lesion.

SRI - Speckle Reduction Imaging*

A type of image noise or interference is generally considered undesirable and can obscure the quality
or interpretation of B-mode images. Although somewhat associated with the underlying echogenicity of
tissue scatters, image speckle characteristics such as brightness, density or size have no apparent
value in determining tissue structure or related properties. The elimination of or significant reduction in
speckle improves the quality or diagnostic potential of the image.
The method applied in the subject modification utilizes a nonlinear diffusion filtering technique that
permits effective speckle reduction in real time. The speckle reduction filter is available to the user in all
B-mode imaging, independent of the transducer used.
