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.
