An X-ray system arranged for providing X-ray exposure to a target volume comprising an X-ray source and at least one focusing lens wherein said exposure is distributed over a volume of said target in a substantially uniform manner.
An X-ray system arranged for providing X-ray exposure to a target volume;
- said system comprising
- (a) an X-ray source;
- and,
- (b) at least one focusing lens configured for focusing radiation emitted by said source, said lens being axially symmetric;
- said lens comprising Bragg-type lens elements longitudinally arranged for Bragg X-ray diffraction of said radiation;
- wherein an emitting aperture of a variable shape of said source is extendable such that said lens provides a substantially uniform convergent X-ray beam of a controllable waist size comparable with dimensions of said target volume.
The X-ray lens configured for focusing radiation emitted by said source, said lens being axially symmetric;
- said lens comprising Bragg-type lens elements longitudinally arranged for Bragg X-ray diffraction of said radiation;
- wherein a reflecting surface of said focusing lens configured into a tiled structure, at least one cell of said tiled structure has a convex surface of a predetermined negative radius, so that said cell diffracts incident X-rays into a diverging sub X-ray beam.
A method of providing X-ray exposure to a target volume wherein said exposure is distributed over said target volume in a substantially uniform manner.
A method of providing X-ray exposure to a target volume;
- said method comprising the steps of:
- (a) providing a system arranged for providing X-ray exposure to a target volume;
- said system comprising
- i. an X-ray source;
- and,
- ii. at least one focusing lens configured for focusing radiation emitted by said source, said lens being axially symmetric;
- said lens comprising crystal lens elements longitudinally arranged for Bragg X-ray diffraction of said radiation;
- (b) emitting X-ray radiation;
- and,
- (c) focusing said emitted radiation by said focusing lens within said target volume;
- wherein said radiation is emitted by an extendable aperture of a variable shape of said source;
- said radiation is converted into a substantially uniform convergent X-ray beam of a controllable waist size comparable with a size of said target volume.
