Abstract: The installation according to the invention practically eliminates the total irradiation of the radiologic examinated persons, using an X radiations source, which produces a swept filiform beam, synchronized with the sweep of a T.V. monitor. In this way the useless irradiation of the entire examined surface is avoided with a strict exception of a single image point useful at one given moment, image point which is transmitted to the T.V. monitor.There are given more achievement variants of the swept filiform beam, as: radioopaques screens with punctiform orifices or slits and radiodiagnosis tubes with swept emission point of the X radiation associated with antidiffusion grids which turn the swept X radiations beam into a swept filiform X radiations beam.The radiodiagnosis tube with swept emission point of the X radiations is utilized also for the achievement of a tomoscopy or an electronic tomography with the wipe in surface.
