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.
