Radiologists can significantly reduce radiation exposure during image-guided spine interventions using lead shielding and optimal positioning. These methods, based on radiation physics, achieve dose reductions up to 98.7%.

Area of Science:

  • Medical Imaging
  • Radiology
  • Interventional Procedures

Background:

  • Image-guided spine interventions are increasingly common.
  • Physicians performing these procedures face potential radiation exposure.
  • Mitigating radiation dose is crucial for patient and staff safety.

Purpose of the Study:

  • To assess techniques and devices for reducing radiation exposure during spine interventions.
  • To evaluate the effectiveness of shielding methods in minimizing radiation dose.

Main Methods:

  • Measurements were conducted on a humanoid phantom.
  • Various stationary and mobile lead shielding methods were tested.
  • Operator positioning was analyzed as a radiation mitigation strategy.
