The sample is excited at once with the primary cone-beam X ray source and fluorescent X-rays emitted from the surface are recorded through coded-aperture with position- and energy-sensitive detector. This approach eliminates...

The main advantage of proton therapy over conventional radiotherapy is the scheme of dose deposition: unlike X-rays, protons are fully stopped in patient’s tissues with a distinct maximum at the end of their range: the Bragg peak. Such a distribution allows for a precise coverage of a tumor volume while sparing the nearby healthy tissues. However, accurate control of the proton beam range is...
