This study introduces a robot system for remote ultrasound diagnosis. It uses haptic feedback to allow experts to control a distant ultrasound probe, improving hand-eye coordination for better medical examinations.

Area of Science:

  • Robotics
  • Medical Imaging
  • Haptics

Background:

  • Remote medical diagnosis presents challenges in maintaining operator dexterity.
  • Echographic examinations require precise hand-eye coordination and tactile feedback.

Purpose of the Study:

  • To develop and evaluate a master-slave robotized system for remote echographic diagnosis.
  • To enable remote experts to control ultrasound probes with haptic feedback.
  • To preserve the operator's proprioception for enhanced diagnostic accuracy.

Main Methods:

  • A master-slave robotic system architecture was designed.
  • A virtual probe controlled by a haptic device mimics real probe movements.
  • A slave robot positions the ultrasound probe on the remote patient.
