Radiological Physics
Interventional Procedures

Background:

X-ray fluoroscopy procedures, common in interventional cardiology and neuroradiology, pose radiation risks due to prolonged exposure times.
Balancing sufficient imaging dose for accuracy with minimizing radiation-related risks is a critical challenge.

Purpose of the Study:

To investigate a method for achieving necessary tracking uncertainty in interventional procedures while using the minimal possible radiation dose.
To develop a technique that dynamically optimizes fluoroscopic imaging parameters to control radiation exposure.

Main Methods:

A simple model demonstrated the relationship between imaging dose and tracking uncertainty.
A feedback framework was developed to modulate tube current and maintain required uncertainty.
The framework was evaluated using a particle filter algorithm for fiducial tracking in image-guided radiotherapy.

Main Results:

The feedback framework successfully reduced entrance surface exposure by up to 28.6%.
This dose reduction was achieved while maintaining a geometric tracking uncertainty of 0.3 mm.

Conclusions:

A dynamic optimization technique for fluoroscopic imaging parameters has been identified.
This method effectively controls applied radiation dose by leveraging the trade-off between tracking uncertainty and X-ray exposure.
