Device for concentrating ionizing radiation fluence, which focuses electrons and x-ray photons and is adaptable

An ionizing radiation fluence concentrator device of variable focus adaptative to a high-energy electron source of an external radiotherapy device with linear accelerator, the device comprising:

• a coupling structure adapted to be coupled to an outer structure, the coupling structure comprising an electron window adapted to receive an electron beam;
• a rotation system comprising a hollow central axis adapted to receive the electron beam, the rotation system being coupled to the coupling structure by a fixing means;
• an interior structure coupled to the rotation system, the interior structure adapted to be rotated by the rotation system;
• an electron deflection system disposed in the interior structure, the electron deflection system comprising a first magnetic deflection device adapted to deflect the electron beam and a second magnetic deflection device adapted to deflect the electron beam;
• a focus control system, comprising a set of motors adapted to cause displacements of the second magnetic deflection device, an electronic control system adapted to control the set of motors, and a collimator in a collimation unit adapted to control a position of a focal point;
• and
• at least two laser guides located at an edge of the collimator and pointing towards the focal point, the at least two laser guides adapted to determine an electron beam position.
