Patient radiation doses during fluoroscopic procedures can be high. Effective management involves monitoring exposure rates and using dose reduction techniques like pulsed fluoroscopy for patient safety.

Area of Science:

  • Medical Imaging
  • Radiology
  • Radiation Safety

Background:

  • Fluoroscopic procedures, especially interventional ones, can lead to significant patient radiation doses.
  • Radiation dose is influenced by numerous factors including procedure type, patient size, equipment, and technique.

Purpose of the Study:

  • To highlight the importance of assessing fluoroscopy system performance regarding radiation dose.
  • To discuss methods for managing patient radiation exposure during fluoroscopic procedures.

Main Methods:

  • Characterizing fluoroscopy system performance using receptor and skin entrance exposure rates.
  • Clinical monitoring of patient doses and exploring direct skin dose measurement.
  • Implementing various dose reduction techniques.
