Summary
This study on interventional radiology found that copper filtration and specific X-ray beam angles increase radiation dose coefficients. However, lead curtains and suspended shields significantly enhance physician protection, reducing exposure by over 358%.
Area of Science:
- Medical Physics
- Radiological Protection
- Diagnostic Imaging
Background:
- Interventional radiology (IR) procedures involve significant radiation exposure for both patients and medical staff.
- Accurate estimation of effective doses and entrance skin doses is crucial for radiation safety in IR.
- Variations in procedural parameters can influence radiation dosimetry.
Purpose of the Study:
- To investigate the impact of filtration, X-ray beam projection angle, and shielding on radiation dose coefficients in interventional radiology.
- To quantify the effectiveness of lead curtains and suspended lead glasses in protecting physicians during IR procedures.
Main Methods:
- Utilized MCNPX 2.7.0 radiation transport code for computer simulations.
- Modeled a realistic interventional radiology room scenario using MASH virtual anthropomorphic phantoms for patients and physicians.
- Simulated variations in copper filtration, projection angles (lateral, cranial, caudal), lead curtain, and suspended lead glass.
Main Results:
- Addition of copper filtration increased conversion coefficients for air kerma-area product (CCE) and entrance skin doses (CCESD).
- Lateral, cranial, and caudal projections resulted in the highest CCE values due to increased scattered radiation reaching the physician.
- Combined use of lead curtain and suspended lead glasses improved physician protection by 358%.
Conclusions:
- Filtration and projection angles significantly affect radiation dose coefficients in IR.
- Lead curtains and suspended lead glasses are highly effective in reducing physician radiation exposure.
- The presented dose coefficients provide valuable data for calculating effective and entrance skin doses in clinical settings.
