Fan-Beam Based Virtual Fluoroscopy for Navigated Catheterization in Interventional Radiology.

Area of Science:

• Medical Imaging
• Interventional Radiology
• Radiation Safety

Background:

• Interventional radiology offers less invasive procedures than surgery.
• Concerns persist regarding radiation exposure for patients and medical staff.
• Accurate tracking of instruments is crucial during image-guided interventions.

Purpose of the Study:

• To propose a novel concept for significantly reducing X-ray irradiation dose during instrument tracking in interventional radiology.
• To maintain accurate localization of tools within the patient during procedures.

Main Methods:

• Integration of a miniaturized X-ray detector into the tip of interventional tools.
• Implementation of a "rotating collimator" system to control X-ray beam.
• Real-time processing of signals from the detector for tool localization.

Main Results:

• Demonstrated accurate real-time localization of the tool tip.
• Achieved a significant dose reduction of at least ten times.
• Validated the feasibility of the proposed concept for radiation dose reduction.

Conclusions:

• The novel concept effectively reduces X-ray dose in interventional radiology.
• This approach enhances safety for both patients and healthcare professionals.
• Personalized medicine can benefit from reduced invasiveness and radiation exposure.
