Depth/Zoom
A dual-function control that activates one function when the control is
rotated and another function when the control is pressed and then rotated.
Rotating the
DEPTH/ZOOM
control changes the imaging depth.
For software versions 1.2 and higher: Rotate the
DEPTH/ZOOM
control
clockwise to decrease depth and counterclockwise to increase depth.
For software version 1.0: Rotate the
DEPTH/ZOOM
control clockwise to
increase depth and counterclockwise to decrease depth.
The depth scale displays in millimeters (mm), and the current depth setting
displays on the lower left of the image screen.
Pressing
DEPTH/ZOOM
activates a zoom window in the image, initiating
the magnification process. Zoom is available in real-time or when the image
is frozen.
Note:
The zoom window appears highlighted in green when active.
Rolling the trackball positions the zoom window over the region of interest
(ROI). Rotating
DEPTH/ZOOM
adjusts the size of the window. Pressing
DEPTH/ZOOM
again magnifies the selection. To exit zoom, press the
2D
control.
When Zoom is activated, the ROI of a real-time or frozen image can be
moved by rolling the trackball.
Focus
The
FOCUS
control positions the transmit focal zones in the image. One,
two, or four focal zone markers can be positioned at the same time.
Mechanical sector transducers have a fixed focus.
Note:
When two or four focal zones are used, a reduction in frame rate occurs. The
amount of reduction depends on the depth of view and the transducer in use.
Push the
FOCUS
control up or down to position the focal zone markers that
represent the focal zone locations.
One (1)
You can position the marker throughout the field of view.
Two (2)
The spacing between the two focal zones adjusts automatically.
Four (4)
The
FOCUS
control adjusts the relative position of the focal zone markers
within the field of view. The spacing between the focal zones
adjusts automatically.
