APPARATUS FOR PERFORMING NANOPARTICLE-ASSISTED EXTERNAL BEAM RADIOTHERAPY

摘要

An apparatus for performing nanoparticle-assisted external beam radiotherapy comprising an X-ray spectrometer (SPM) having an optical axis (SOA), an X-ray filter (F), and a mobile holding structure (MHS) suitable for holding the X-ray filter and the X-ray spectrometer in a first and a second relative position, and for switching from said first to said second relative position while simultaneously allowing the positioning of a patient body part (PB) in a target region including a target point (TP); wherein: the first and second relative positions of the X-ray filter and the X-ray spectrometer are such that an X-ray beam (XRB) emitted from the X-ray source crosses the X-ray filter before reaching the target point, a propagation direction (PRD) of the X-ray beam forming an angle θ different from 0° and 180° with the optical axis of the X-ray spectrometer; and the second relative position is obtained by inverting the relative positions of the X-ray filter and of the X-ray spectrometer with respect to the patient body part.
