Figure 1.4: The disposition of the simulated arterial structures (blood, intima,
media, and adventitia) and calcification are illustrated. The ultrasound rotatory
transducer, which emits the pulse
P
o
and receives pulse
P
1
, has been placed at
the coordinate center.
Figure 1.5:
The determination of the distance
D
between the emitter/receiver
and the reflecting object is made from the difference of time interval between the
transmitted pulse
P
o
and the received pulse
P
1
, assuming that the pulse speed
c
is constant.
