Integrated Services Digital Network(ISDN)
A typical circuit-switched network system (circuit-
switching network).
Is popular in Europe in the form of a telephone
network.

Robotic armThe system was designed for optimal use with sector
scan probes.The weight of the probe holder (2.5 kg) and with a ring
of 7 cm in diameter.Applies a pressure (15N) and maximum displacement is
1.5 cm.

Results(1/3)
The system is easy to use
The expert (radiologist, obstetrician, midwife)
needed no more than 1 hr to become familiar
with the system.

satellite link communication
Transferring pictures will be delayed one
second.
Robot activation setup took 10–15 min

IBS LAB
Results(3/3)
The mean duration of the conventional
ultrasound examination was 14 min.
Fetal tele-echography
Fetal tele-echography was 18 min.
The robotic arm was repositioned on the patient’s skin
was 7min12

The surgical robotic arm
The surgical robotic arm is reproduce very
accurately the complex movements of the
surgeon’s hands

IBS LAB
Discussion(2/2)
Robotic-surgery is probably the most
popular application of robotics in medicine.
Telemedicine also needs more
improvement.
