Aims and objectives
The use of X-rays for medical purposes carries with it an inherent risk of exposing patient,
surgeons and supporting medical staff members to harmful ionizing radiation.
As the popularity and difficulty of X-ray guided interventional procedures are increasing,
so are the risks of overexposure to ionizing radiation for patients and staff.
Countless studies have shown that any amount of exposure increases the risk of radiation-induced tissue reactions (epilation,
Methods and materials
A radiation awareness demonstrator system has been implemented in an experimental interventional room at IHU Strasbourg,
containing a robotized X-ray imaging device.
It relies on multiple registered RGBD cameras mounted to the ceiling of the room,
along with radiation simulation and visualization approaches (described below),for providing real-time visual feedback about the current propagation of scattered radiation and the patient and attending personnel dose.
The views from the ceiling...
Demonstrations of our prototype radiation awareness system have been performed to our collaborating clinical and industrial partners.
Initial feedback has been positive since the system provides in-situ feedback about radiation exposure in an interventional room in an intuitive manner.
The potential of the system to be employed as a tool to teach about radiation's diffusion effects has also been acknowledged in the demonstrations.
using such a system would enable to teach trainees in...
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...
