Measurement
You can perform measurements on zoomed images, cine reviewing images, real-time images or
frozen images. For measurement details, see the [Advanced Volume].
WARNING:
Be sure to measure areas of interest from the most optimal
image plane to avoid misdiagnosis arising from inaccurate
measurement values.
To obtain accurate Doppler flow measurement values, make
sure the transmitting beam is not perpendicular to the flow as
this may lead to false readings and potential misdiagnosis.
CAUTION:
If an image is unfrozen or the mode is changed during a measurement,
the calipers and measurement data will be cleared from the screen.
Measurement data will be stored in the report.
If the system is turned off or <End Exam> is pressed during a
measurement, unsaved data will be lost.
In dual-B imaging mode, the measurement results of the merged image
can be inaccurate. Therefore, the results are provided for reference only,
not for confirming diagnoses.
You can create user-defined measurement tools using the UltraAssist tool and then import them
into the ultrasound system to carry out specific measurements.
For details about this feature, see the UltraAssist manual.
