Semi - automatic positioning of the protective screen based on integration with C-arm X-ray device

In fluoroscopy guided interventional procedures, ceiling suspended screen is used to protect personel for scattered X-ray radiation arising from patents. The correct positioning of the screen is crucial for proper occupational radiation protection. The proposed solution in this paper provides reliable and efficient protection from scattered radiation, based on X-ray device and the protective screen merging into one system via an appropriate interface. After the initial manual positioning, automatic repositioning of the screen is ?xecuted, by curving the screen laterally, clockwise or counterclockwise, and then with the upper or lower edge forward. All potential clinical situations were analyzed, considering need for screen position correction: the semi-automatic solution is designed and realized to follow the medical procedure in order to keep the efficient level of staff radiation protection. Furthermore, the assessment of the occupational radiation dose, provided for screen position optimization, will be imported in the radiation dose structural report. With application of the universal interface, the presented solution can be applied not only on newly manufactured ones, but on existing C-arm X-ray devices as well.
