We have presented a system for improving radiation safety in the interventional room by making ionizing radiation visible. The system has been positively received by our collaborating interventional radiologists since it provides a clear in-situ visualization of radiation. The simulations have been validated experimentally using active personal dosimeters, yielding a mean 18% difference between simulated and measured values. The obtained results showed that the error between the simulated and measured dose values is in agreement with the intrinsic error of the dosimetric system we use.


Intraoperatively, our system can contribute to increase radiation awareness and reduce overexposure risks for patients and staff. Also, clinicians can adapt their positioning and the disposition of protective equipment with the provided visual feedback. Preoperatively, it has the potential to be used as a teaching tool to teach about ionizing radiation diffusion effects and the best safety practices.


Better awareness to ionizing radiation and reduced exposure can lead to greater acceptance of minimally invasive procedures and hybrid rooms that heavily depend upon the use of X-ray imaging technologies, and are planned to be routinely utilized by clinicians from a variety of disciplines. Consequently, improving radiation safety can facilitate a greater and a safer access to X-ray-guided minimally invasive procedures.
