Velocity Measurement
Velocity of a moving structure is the rate of change of its
displacement. It is determined by placing an arbitrary
line tangent to the steepest slope of the structure in a
M–Mode trace and measuring its slope which is equal to
the velocity of the structure. It is expressed in meters per
second.
As in all M–Mode measurement freeze before performing
any measurement.
Press
MEASUREMENT to display the General
Measurement Menu. Simultaneously an open ended “ ”
appears on the screen.
Select [3].
If the appropriate measurement was already performed
the Velocity is calculated and displayed.
Use the
TRACKBALL to move the open ended “ ” cursor
to a point tangential to the steepest slope of the M–Mode
trace.
Press
SET set to fix one end of the line. A second cursor
and a dotted line appears.
Use the
TRACKBALL to move the second open ended
“ ” cursor to a point such that the dotted line is tangential
to the steepest slope of the M–Mode trace of the
structure of interest.
Press
SET. The velocity of the structure is displayed at
the right side off the screen.
Up to four measurements values can be displayed on
the screen.
