Dosimetry of portable image intensifiers in pacemaker insertions
Catheterization and Cardiovascular Diagnosis
|January 1, 1975
Summary
Portable image intensifiers used in pacemaker insertions pose radiation risks to staff. The thyroid and eye lenses receive substantial radiation doses, necessitating safety recommendations for personnel protection.
Area of Science:
- Medical Imaging
- Radiation Safety
- Cardiology
Background:
- Increasing use of portable image intensifiers in pacemaker procedures.
- Need to assess radiation exposure risks for healthcare professionals.
Purpose of the Study:
- Investigate radiation hazards to operative personnel during pacemaker insertions.
- Quantify radiation doses to critical organs.
Main Methods:
- Utilized a Rando phantom for initial testing.
- Monitored radiation exposure during actual pacemaker insertion procedures.
Main Results:
- Identified thyroid and eye lens as critical organs for radiation exposure.
- Measured approximately 15mR to the thyroid and 13mR to the eye lens per procedure.
- Radiation doses were substantial, though within the weekly Maximum Permissible Dose (MPD).
Conclusions:
- Operative personnel face significant radiation exposure during pacemaker insertions using portable image intensifiers.
- Radiation dosage may increase under different operating conditions.
- Recommendations are provided to enhance safety protocols and minimize exposure.
