Realtime Trace
Calc Dir.
Description
Automatically traces (real-time) the
parameter selected in the Set Up/Custom
Display Menu page 15. The choices are
Peak, Floor, Mean, and Mode. (Also found
in the CWD soft menu.)
Choose which part of the Doppler Trace
will be used for automatic measurements/
calculations. (Also found in the CWD soft
menu.)
Benefits
No need to manually trace a selected
value. Measurements and calculations will
be automatic.
Easy access to change which portion of
the Doppler Trace is used for automatic
measurements/calculations.
Values
OFF
RealTime Trace is turned off.
ON
RealTime Trace is active.
NOTE: If the Realtime Doppler Calculation
option is not installed, the CALC selection
will not be available.
CALC
RealTime Trace is active and
measurements/calculations are
displayed.
Trace and calculations are done internally,
even if RealTime Trace is turned off. After
the image is frozen, change the RealTime
Trace to ON or CALC to display the trace
and calculations.
Compo
Composite—Uses both forward
and reverse flow data.
Fored
Forward—Trace only data
towards the transducer.
Revrs
Reverse—Trace only data away
from the transducer.
Hints
The best Doppler data is collected when
parallel to flow, with orientation also
parallel to the anatomic target; whereas,
the best B-Mode image data is collected
perpendicular to the anatomic target.
Therefore, there usually is not both an
ideal B-Mode image and ideal Doppler
data simultaneously.
