Abstract: An X-ray system comprises: (a) a source providing an X-ray diverging beam having treatment and imaging angular portions; (b) one or more lenses transforming the treatment portion of the X-ray beam into a converging beam directed to a target; (c) a first shutter located between the X-ray source and the target in the imaging portion of the X-ray radiation; the first shutter being selectively openable such that imaging portion of X-ray beam reaches the target; and (d) a detector configured to detect at least a portion of the imaging radiation after the imaging radiation has interacted with the target to provide imaging information of the target.

Abstract: The present invention provides a method for activating a pro-drug in vivo comprising the steps of: (a) administering a pro-drag to a subject; (b) locating a target site which has been at least partially dosed with the pro-drug at a predetermined concentration; and (d) exposing the target site to X-ray radiation. The step of exposing the target site to X-ray radiation is characterized by providing a converging X-ray of a controllable waist, substantially uniform at the target site, sufficient to convert the pro-drug to an active drug, while the X-ray photon dosage at the target site is higher than the X-ray photon dosage at an adjacent non target site.

Abstract: An X-ray lens arrangement for forming a radiation pattern as a focal track is disclosed. The pattern comprises at least one 3-dimensional focal track of radiation. The aforesaid lens arrangement has a main axis passing through intensity weighted centroids of the X-ray source and the pattern. The lens arrangement includes at least one reflecting surface of continuously varying Rowland arcs. Each point belonging to the focal track is linked to each elemental point composing an emitting surface of said source by a corresponding Rowland arc.

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-Dimensional depth dependence of said maximal doses obtained from said number of transversal dose distributions.
