Abstract: A method of evaluating a maximal dose deposited by an X-ray beam within a medium comprises the steps of: (a) irradiating said medium by said X-rays beam penetrating into a depth of said medium along an axis of said X-ray beam; (b) measuring a dose distribution along said axis. The step of measuring said dose distribution further comprises measuring cross-sectional distributions with a predetermined incremental shift thereof along said beam axis, and calculating a 1-dimensional function of said maximal dose in dependence on said depth taken from maximum dose at each cross-sectional distribution at each depth.

Abstract: An X-ray system comprises: a source of an X-ray diverging beam having a central imaging portion and a peripheral treatment-portion; a lens transforming the peripheral treatment portion of the X-ray beam into a converging beam directed to a target; a shutter located between the X-ray source and the target in the central imaging portion of the X-ray radiation; and a detector of imaging radiation after interaction with the target and to provide imaging information of the target.
