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.

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 translation: 本发明提供了一种活体内激活前体药物的方法，其包括以下步骤：（a）将前体药物施用于受试者; （b）将已经至少部分用前药给药的靶位点定位在预定浓度; 和（d）将目标部位暴露于X射线辐射。 使目标部位暴露于X射线辐射的步骤的特征在于提供可控腰部的会聚X射线，其在目标部位基本均匀，足以将前药转化为活性药物，而X射线 目标部位的光子剂量高于相邻非目标部位的X射线光子剂量。

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.
