X-ray irradiating device used in cancer treatment to destroy a tumor in the body comprises a collimator arrangement with a collimated X-ray beam having an adjustable shape and/or width

摘要

X-ray irradiating device (1) comprises a collimator arrangement (3) structured so that the shape and/or width of the collimated X-ray beam (R) and/or the direction of the beam from the X-ray source (2) can be adjusted about the irradiated object (O) in a defined manner. The X-ray irradiating device has a collimator control unit (10) for controlling the collimator arrangement during use so that the shape and/or width of the collimated X-ray beam and/or direction of the beam from the X-ray source is fitted to the position and/or cross-section shape of the irradiated object with respect to the actual position of the X-ray source. An independent claim is also included for a method for producing collimated X-ray beams for irradiating an object.
