5.1.4.14 SRI Advanced - 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 used probe.
5.1.4.15 V-SRI Advanced - Speckle Reduction Imaging
V-SRI is an enhancement of the existing SRI algorithms and improves specially the C-plane image. This new
algorithm (from Context Vision) is used in the A-, B-, C-planes and rendered images instead of the
conventional SRI.
Note The “V-SRI” option is only available at Voluson E10 systems with probe RM6C, RIC5-9-D and RIC6-12-D.
5.1.4.16 SonoMetrium
SonoMetrium allows automated detection and display of a rendered Uterine C-plane and thereby 3D
analysis of the endometrial cavity in application Gyn.
This option is only available for Voluson E-Series systems with software version EC330 (BT18).
5.1.4.17 eM6C - E4D Activation (Advanced Features for Electronic 4D Matrix-Probe)
After entering an encrypted Software Option string (password) it is possible to use the Electronic 4D Matix-
Probe eM6C with all the advanced features such as Bi-Plane Mode and
e
STIC.
Note
The “eM6C” option is only available at Voluson E10 systems.
5.1.4.17.1 eSTIC
The intended use and workflow of the
e
STIC acquisition mode is the same as the standard STIC mode but
with the advantage of a faster acquisition time.
Note “eSTIC” is only available with probe eM6C.
5.1.4.18 CW - Continuous Wave Doppler
CW Doppler mode provides real time spectral analysis of CW Doppler signals. This information describes the
Doppler shifted signal from the moving reflectors in the CW Doppler beam. CW Doppler can be referenced
through a small pencil probe or phased array scan head, but it can also be used in conjunction with a 2D
image which has an M-line superimposed on the 2D image indicating the position of the Doppler sample
volume. For through-the-beamformer CW, this beam is steerable by the operator, and is done by adjusting
the location of the M-line. The CW Doppler beam, or M-mode line, can be steered allowing interrogation
along an operator-selected line within the image.
Note Additional hardware is required at EC300/EC310 (BT15/BT16) system!
5.1.4.19 SW DVR - Software Digital Video Recording
After entering an encrypted Software Option string (password) it is possible to record Ultrasound data on
DVD or an USB device. Videos are created in .mp4 file format.
5.1.4.20 DVD and USB Recorder
After entering an encrypted Software Option string (password) it is possible to record Ultrasound data on
DVD or an USB device. Videos are created in .mp4 file format.
This option is only available for Voluson E-Series systems with software version EC330 (BT18).
