5.1.4.8.1 Elastography Analysis
A selectable sequence of Elastography images are analyzed within a ROI (range of interest). The Strain %
or the Elasticity Index is displayed as curves over the time.
The mean value of the Strain % is measured within 1 or more ROI’s and Ratios are calculated. “Generic
Elasto” measurements are located in the generic measurement menu and are only available if
“Elastography” is activated.
5.1.4.9 SonoVCAD heart - Computer Assisted Heart Diagnosis
VCAD is a technology that automatically generates a number of views of the fetal heart to make diagnosis
easier. At this time it can help to find the right and left outflow tract of the heart and the fetal stomach.
Note
“SonoVCAD heart” is part of the “Advanced STIC” option for Voluson E8 and Voluson E10 systems. At
Voluson E6 systems it is optional (separately purchasable).
5.1.4.10 SonoAVC - Sono Automated Volume Count
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. From the calculated volume an average diameter can be
calculated. It also lists the objects according to their size.
•
Each object can be calculated automatically.
•
A description name can be defined for each object up to 10 descriptions. With the “Add to Report”
button all values of the measured objects can be sent to the worksheet. Also the description name will
be sent.
•
The description name can be edited in the worksheet.
•
If the number button is activated, all objects are assigned a number inside the displayed object
according to the measurement index.
•
Group function: All objects will be added to one volume. The color of all objects will be changed to red
and the measurement will show only one result.
5.1.4.11 SonoVCAD labor
Allows the user 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.
All SonoVCAD
labor
measurements (Head direction, Midline Angle, Progression Distance, Progression
Angle and associated acquisition time) are automatically added to the worksheet, as soon as they are
performed. Only one measurement result is available for each measurement type. If the measurement is
repeated, the old result is replaced by the new result.
If a volume is deleted, the according measurements are not deleted from the worksheet.
SonoVCAD
labor
measurement data can be transferred via DICOM SR.
5.1.4.12 Anatomical M-Mode (AMM)
Anatomical M-Mode displays a distance/time plot from a cursor line, which can be defined freely. The M-
Mode display changes according to the motion of the M cursor. In the Dual format, two defined distances can
be displayed at the same time.
AMM is available in grayscale and color modes (CF, HD Flow, TD)
•
simultaneous Display of 2 M-Mode Cursors in 2D Mode
•
each Cursor is freely rotatable
•
can be done after Freeze and on reloaded Cine
