Abstract: A method of evaluating a maximal dose deposited by a non-uniform X-ray beam within a medium comprising the steps of: (a) irradiating said medium by said non-uniform X-ray beam penetrating into a depth of said medium along an axis of said X-ray beam; (b) incrementally measuring a number of transversal dose distributions at successive depths along said axis; (c) determining a maximum dose within each of said number of transversal dose distributions; and (d) calculating a 1-Dimesional depth dependance of said maximal doses obtained from said number of transversal dose distributions.

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 for providing a converging X-rays comprising: (a) an X-ray source having an optical axis thereof; (b) an X-ray lens arrangement comprising at least one first ring having a first Bragg reflecting surface formed by a plurality of tiles made from single crystal. At least one ring is provided with at least one second ring mounted adjacently thereto along said optical axis in a coaxial manner; said second ring has a second Bragg reflecting surface reflecting surface thereof.
