DEVICE FOR GENERATING BEAMS OF CONVERGING X-PHOTONS AND ELECTRONS

摘要

The invention relates to scientific/technological equipment intended for the generation of a beam of converging photons for use in radiotherapy or other applications. The equipment is used for suitably forming, by means of the application of magnetic and/or electric fields, a beam of electrons originating from a linear accelerator (LINAC), which electrons perpendicularly intercept the surface of a curved material of a particular radius of curvature (anode), thereby generating X-rays. The interaction between the electrons and the atoms of the anode material generates X-rays with a non-isotropic angular distribution having a greater concentration in the focal direction and being defined by the geometry of the anode. A curved collimator is located at the rear part of the anode, said collimator having a suitable radius of curvature and being formed by an arrangement of a large number of small holes pointing towards the focal point. The device allows the transmission of X-rays only in the focal direction. A typical diagram of the invention is provided in the figure.
