A new robotic system precisely places brachytherapy needles for prostate cancer treatment. This robot-assisted approach enhances accuracy and patient care by minimizing needle deflection and target movement.

Area of Science:

  • Medical Robotics
  • Oncology
  • Surgical Technology

Background:

  • Accurate needle placement is crucial but challenging in brachytherapy.
  • Current brachytherapy techniques face limitations in precision and control.
  • Robot-assisted systems offer potential for improved needle placement and seed delivery.

Purpose of the Study:

  • To develop and fabricate a novel robotic system for prostate brachytherapy.
  • To enhance needle placement accuracy and seed delivery in brachytherapy procedures.
  • To incorporate techniques for reducing needle deflection and target movement.

Main Methods:

  • Development of a 16 degrees-of-freedom (DOF) robotic system with separate positioning and surgery modules.
  • Implementation of experimental verification for techniques reducing needle deflection and target movement.
