Velocity (mm/second)
VELOCITY is the difference in tissue depth (range of
tissue motion) divided by the elapsed time captured in
the M-Mode image or B/M-Mode. If calculations are
done in the wrong mode, an error message VEL ILG will
appear in the Calculation Result Area. Velocity
calculations are measured as moving mm/second.
Velocity= Height of a Wave/Elapsed Time.
Select [4] in the Sub Menu. If the sub menu was used for
a prior calculation, the system defaults back to the sub
menu when
MEASUREMENT is pressed.
Use the
TRACKBALL to move the M-Mode measurement
cursor to the start point of the measurement.
Press SET to fix the start point. A second M-Mode
measurement cursor appears.
Use the
TRACKBALL to move the cursor to the end point
of the measurement.
Press SET to fix the end point. Should further
measurements need to be taken, press SET again to
invoke the second cursor and follow the procedure as
indicated above. Four calculations can be taken at the
same time.
