Robotic assistant for transperineal prostate interventions in 3T closed MRI

Area of Science:

• Urology
• Medical Robotics
• Oncology

Background:

• Image-guided needle-based therapies are crucial for prostate cancer management.
• Transrectal ultrasound (TRUS) guided interventions face limitations in accuracy due to image fidelity and needle-tissue interaction.
• Magnetic Resonance Imaging (MRI) offers superior visualization of prostate anatomy.

Purpose of the Study:

• To design and evaluate a comprehensive robotic assistant system for prostate interventions.
• To enable prostate biopsy and brachytherapy procedures entirely within a 3T closed MRI scanner.
• To assess the usability and MR compatibility of the designed robotic system.

Main Methods:

• Development of a novel robotic manipulator for MRI-guided procedures.
• Integration of the robotic system within a 3T closed MRI scanner environment.
• Evaluation of the system's usability and magnetic resonance (MR) compatibility.

Main Results:

• A comprehensive robotic assistant system was successfully designed.
• The system facilitates prostate biopsy and brachytherapy entirely within the MRI scanner.
• Initial evaluations indicate good usability and MR compatibility of the robotic manipulator.

Conclusions:

• The developed robotic system holds promise for enhancing the accuracy and capabilities of MRI-guided prostate interventions.
• This technology could improve the management of prostate cancer through precise biopsy and brachytherapy.
• Further research and clinical validation are warranted to fully realize the potential of this robotic platform.
