Summary/Abstract: Objective: The increasing use of image-guided interventional procedures in medical practice led to increasing patient doses of radiation and to increasing concern over staff doses. This study describes the method of offline visualization of x ray radiation during interventional neuroradiology procedures. Materials and methods: Scattered radiation measurements were acquired by using two alarm digital dosimeters (Stephen 6000 series digital dosimeter, Centronics Ltd, Croydon, England). Stray radiation air kerma rates were recorded in three planes (x, y and z). Isodose curves were generated using logarithmic interpolation from the measured data points. Results: Isodose curves acquired in three planes were connected in 3D object representing radiation, colour encoded. The colours were added to the 3D mushroom of radiation in respect to the measured doses. 3D radiation object than was offline projected over pictures (photography’s) and movies of staff during procedures. Conclusion: Pictures and movies with projected 3D object representing radiation during image-guided interventional radiology procedures were alarming close representation of scattered radiation, offline and in the specific moment of procedures. The primary goal was visualization of radiation during the procedure, without any idea of calculating total level of scattered radiation during the procedure. Using newest technology (lasers, holography and strong computers) it is possible to develop new kind of devices for the real time visualisation of scattered radiation for the use of staff involved in the procedures.
