M-STB Index
Motion stability indicates the degree of motion interference, and reflects the motion interference
degree of the currently-captured elasto image and if the elasto image is stable and reliable. Thus, it
is helpful for the doctor to determine if the current image is suitable for reference.
The elastography imaging can be easily affected by respiration, pulse of the main artery, or
transducer movement, which may cause uncertainty and unreliability. The M-STB Index helps
users judge whether the current elasto image is captured in stable state. Based on the judgment,
capturing method, capturing part, and patient cooperation can be adjusted accordingly.
After the feature is enabled, M-STB Index is displayed on the 2D image.
Tap [Breath Sensi.] on the touch screen to set the grading threshold of M-STB Index. The higher
the sensibility of the motion stability is, the higher the judgment accuracy of the motion
interference becomes.
Breath Sensi.
Adjust the availability of the Elastography Imaging. The higher the motion sensibility is, the greater
the image availability is.
