“…To compare the difference of patient radiation doses between the field intervention cabin and a cardiac catheterization lab, a simulation was performed on a radiation simulation irradiated human model (standard plexiglass 200 mm × 200 mm × 30 mm Model VD0203510, IBA Dosimetry GmbH, Germany) [9, 10]. The radiation simulation irradiated human model was exposed on all available image intensifier sizes as well as with a clinically suitable collimation.…”

BackgroundMinimally invasive surgery in the field of traumatic vascular injury diagnosis and treatment has achieved good results. This study was designed to determine whether pre-hospital emergency intervention is feasible for vascular injury in a field intervention cabin under the condition of war or a disaster site.MethodsDifferent types of animal experiments of vascular injury intervention were performed in a field intervention cabin. Treatment capacity was evaluated by data collection, including duration of surgery, clinical evaluation, image clarity, and equipment handling. Environmental adaptability and mobility were evaluated by maneuverability and long-distance mobility.ResultsA total of 56 surgeries (7 types) were performed in the field intervention cabin. Digital subtraction angiography (DSA) had good imaging performance. A total of 4800 km of long-distance mobility was performed, and all the equipment operated normally without any equipment failure. We participated in the medical service maneuver twice. The cabin unfolded and worked properly. There was no equipment damage during the medical service maneuver.ConclusionsUse of a field intervention cabin under the conditions of war or disaster is feasible for pre-hospital emergency intervention of vascular injury.

“…This is one of the most important topic in radiation protection of personnel at medical application of ionizing radiation, including PET-CT diagnostics [15][16][17][18]. Major source of occupational exposure here is radiation scattered from the patient [4,10,13,14,[19][20][21][22]. In order to keep radiation dose as low as possible, suitable personal and collective protective tools must be used, including use of ceiling suspended screens.…”

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.

For the photon transport kernel in form of the Thomson scattering function and a restrictive photon diffusion directed only toward free surface, several exact expressions of back scattered fluxes are demonstrated. The solving approach was established on a lemma proved by Placzek combined with the Fourier analytic inversion technique or the order of scattering method. Albedo problem in case of the homogeneous plane shield of iron subjected to the photons normally incident on the free surface is treated. Comparison of the results obtained by the analytical and Monte Carlo methods for the reflection of 40 and 60 keV photons from iron target confirms the domination of the single scattered photon flux and the strong influence of the scattering function anisotropy in reflection process at low energies
