Gain Adjusts system sensitivity to received angio signals.
Increasing the angio gain percentage increases the
amount of color displayed.
Magnify Increases or decreases the magnification factor of an
image in Zoom or Zoom Preview modes.
Pan When the Pan control is on, repositioning and resizing
affect the color area.
Scale Changes the range of angio flow velocities whose
amplitude can be displayed. This affects the PRF.
Lower the Scale to see slow flow, and increase it to see
higher velocities.
Steering Steers linear angio images to the right or left to achieve
optimal angio angles. Only available with linear
probes.
Sweep Changes the sweep speed of the ECG waveform.
Available speeds are 25, 50, 100, and 150 mm/sec.
Threshold Eliminates the lowest amplitude signals, allowing you
to adjust the noise level shown in the image. Available
in real-time, and on acquired and retrieved loops.
Zoom
Turns zoom (magnification) on or off. To move the
zoom preview area, use the trackball ( is active
when you first enter zoom preview). To resize the zoom
preview area, press and use the trackball. Then
touch Zoom again to enter full zoom mode.
Tip: When activated,
Zoom is first outlined
by a box. This
indicates zoom
preview. Touch Zoom
a second time to go
into full zoom.
