About Construction Methods
There are two construction methods:
When the
Continuous
method is selected, the Trackball is used to define the
flow pattern or
2D
image with a continuous motion.
When the
Point to Point
method is selected, the Trackball is used to place
points along the flow pattern or
2D
image. Press <
ENTER
> after each point is
positioned and the points will automatically connect. Double-click the last
point to complete the outline.
NOTE When tracing a Doppler flow envelope, the cursor has been pro-
grammed to remain either above or below the baseline.
NOTE The direction of the trace cannot be reversed once started—when
tracing from left to right, the trace can only be completed by continu-
ing towards the right of the flow envelope.
NOTE When defining a portion of a
2D
image, no part of the outline can
intersect another segment of the outline.
