Low-dose CT fluoroscopy-guided interventional minimally invasive robot

Area of Science:

• Medical Imaging and Interventional Radiology
• Robotics in Medicine

Background:

• Assessing the feasibility, safety, and accuracy of novel medical procedures is crucial.
• Traditional CT-guided manual puncture carries risks and limitations.

Purpose of the Study:

• To evaluate a low-dose CT fluoroscopy-guided remote-controlled robotic real-time puncture system.
• To compare the robotic system against traditional manual puncture methods.

Main Methods:

• A phantom experiment and an animal study (four pigs) were conducted.
• The study included a traditional CT-guided manual puncture control group.
• A remote-controlled robotic puncture group was evaluated using the Taguchi method for parameter analysis.

Main Results:

• All simulated and in-vivo targets were successfully punctured without complications.
• Key performance metrics including needle adjustments, puncture time, and radiation dose were analyzed.
• The Taguchi method was employed to optimize and analyze experimental parameters.

Conclusions:

• The robotic puncture system demonstrated safety, feasibility, and accuracy comparable to manual procedures.
• Low-dose CT fluoroscopy-guided robotic puncture is a viable alternative for interventional radiology.
• This technology has the potential to enhance precision and reduce radiation exposure in puncture procedures.
