Abstract: A method of manufacturing burr-edged reflecting tile elements for a mosaic X-ray lens configured for forming an X-ray beam comprises steps of: (a) providing a single crystal having first and second faces thereof being parallel therebetween; single crystal having crystallographic planes thereof being parallel to first and second faces of the single crystal; the first face dedicated for reflecting an X-ray beam to be incident thereto; (b) cutting the single crystal by means of a wire electrical discharging machine normally to the main faces. The step of cutting the single crystal comprises moving a wire within a cut in direction from the second face to the first face; such that burrs configured for reflecting the X-ray beam to be incident thereto are formed on edges of the cut.

Abstract: A radiotherapy treatment system and method used for conducting radiographic X-ray imaging on a target organ during radiographic treatment. The system comprises (a) an x-ray beam source configurable to deliver an X-ray beam to a target organ, (b) optical means for converging and shaping said beam to a cone-shaped X-ray beam of photons which hit the target organ simultaneously, (c) multiple high-Z nanoparticles attachable to the target organ, said high-Z nanoparticles absorbing said X-ray radiation and emitting X-ray fluorescence (XRF) photons, (d) at least one XRF detector for detecting said XRF photons ejecting out of a patient's body, and (e) control means for controlling the radiotherapy treatment procedure.
The x-ray beam is focusable on a section in the target organ where the concentration of said high-Z nanoparticles leading to a desirable emission of said XRF photons, and in case the emission of said XRF photons decreases, the x-ray beam is movable to refocus on the section in the target organ where the emission of said XRF photons is desirable.

Abstract: A method of a radiotherapy or radiosurgery treatment comprises steps of: (a) providing a converging x-ray beam source configured for emitting a converging X-ray beam propagating along an axis thereof; (b) emitting the converging x-ray beam towards a volume of treatment (VOT) having a length along the axis of the converging X-ray beam ranging between 2 mm and 5 cm within a patient's body such that a waist portion is within the VOT; (c) propagating the beam through tissues previously located relative to the VOT (PO); the VOT per se and tissues distally located to the VOT (DO). The converging X-ray beam characterized by a convergent angle ranging between 2 and 30 degrees providing 80% to 100% of a maximum dose is received by the VOT and less than 60% of the maximum dose is received by the PO and the DO.
