Optimizing B-Mode
LOGIQ 7 Online Help 5-17
Direction 2392536-100 Rev. 1
Scan Area
Description You can widen or narrow the size of the sector angle to
maximize the image's region of interest (ROI).
Adjusting To narrow/widen the angle, press Scan Area until Width is
highlighted and move the Trackball left/right to decrease/
increase the angle size. Then press Scan Area to set the ROI.
Values Varies, depending upon the probe (not applicable to linear
probes) and application.
Benefits Increase the sector angle to see a wide field of view; decrease
the sector angle when you need to have a faster frame rate, as
in fetal heart.
Affect on other
controls
Changing the sector angle affects the frame rate. The narrower
the sector angle, the faster the frame rate.
Bioeffects Changing the sector angle may change the TI and/or MI.
Observe the output display for possible effects.
Tilt
Description You can steer the sector angle to get more information without
moving the probe while in B-Mode, M-Mode, Doppler Mode, and
Color Flow Mode.
Adjusting To steer the angle to the left/right, press Scan Area until Tilt is
highlighted, then move the Trackball to the left/right.
Values Varies, depending on the probe.
Benefits Allows you to move a reduced sector angle laterally, without
moving the probe. Beneficial in GYN. It also allows you to vary
the angle so the scan is not perpendicular to the direction of the
flow.
Bioeffects Steering the sector angle may change the TI and/or MI. Observe
the output display for possible effects.
