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. In this purpose the desirable plane of the examinated object is selected by adjustment of the sweep on the T.V. monitor by means of a supplementary deflexion system.
