摘要：
A piece of scientific/technological equipment is presented for the generation of a convergent photon beam for radiotherapy or other applications. This equipment consists of adequately modifying the trajectory of an electron beam from a linear accelerator (LINAC) by applying magnetic and/or electric fields. These electrons perpendicularly impact the surface of a curved material that has a particular curvature ratio (anode), thus generating X-rays. The interactions of the electrons with the atoms of the anode's material generate X-rays with a non-isotropic angular-spatial distribution, with a greater concentration in the focal direction, which is defined by the geometry of the anode. A curved collimator with an adequate curvature ratio is attached to the back of the anode. The collimator is made up of an array of a great number of small holes that point toward the focal point. This device transmits X-rays solely in the focal direction. The Summary Figure presents a typical configuration of the invention that has been presented.
