Chapter 33: Acquiring B-Mode images
Persist
Applies a pixel averaging algorithm to the most recently acquired frames to produce a
more uniform view of the faster moving areas in the image data.
To use this rocker switch control:
Push up or down to cycle through the persistence levels. In the bottom-left corner of the
screen the status bar briefly displays the name of the persistence label as you select.
In B-Mode: Reduces distracting artifacting such as shimmering effects. Levels: Off, Low,
Med, High. This is most useful when you are imaging uniform tissues such as the liver,
kidney and prostate.
Dynamic Range
Adjusts the input signal strength that is mapped into the spectral display. Range: 5-
100dB.
Push up to increase the range by 5dB and lower contrast. Higher dynamic ranges are
often used in cardiac imaging.
Pull down to decrease the range by 5dB and increase contrast. Lower dynamic ranges
are often used in abdominal imaging.
B-Mode
Activates B-Mode acquisition and begins displaying the acquired B-Mode data in the B-
Mode window.
2D Gain
Adjusts the strength of the ultrasound signal when it returns to the face of the
transducer. Range values for the control are specific to each individual transducer.
Turn clockwise to add gain and brighten your entire image. Turn counterclockwise to
reduce gain and darken your image.
