PA-Mode Image Acquisition Workflow on page 165.
B-Mode/PA-Mode Gain
The slider along the bottom of the screen controls gain, but it can control either B-Mode gain or PA-Mode
gain, depending on whether PA-Mode acquisition is active.
If the system is in staging mode (PA-Mode selected, but the Start button was not tapped), then this
l
slider controls B-Mode gain.
When the slider controls B-Mode gain, it appears the same as it does when imaging in B-Mode.
If the system is actively acquiring PA-Mode data (PA-Mode is selected and the Start button was
l
tapped), then this slider controls PA-Mode gain.
When the slider controls PA-Mode gain, the slider features an additional PA label.
Slide either gain control left or right to adjust the visual intensity of the signal received by the face of the
transducer. Slide right to add gain (brightens the image), and slide the slider left to reduce gain (darkens the
image).
When you move the slider, five Time Gain Compensation (TGC) sliders appear on the control panel. Move
these sliders to adjust the gain of the signal at specific depths.
