Beam scanning for dose uniformity

An increase of utilization efficiency of X-ray beam

“…DUR of X-ray depends on energy spectrum and spatial distribution of incident electrons on the X-ray converter. It is a known method of dose uniformity regulation on the target irradiated with scanned electron beam (Mckeown et al, 1995). In accordance with the method, the required dose uniformity in a target along scan direction is realized by varying the waveform of the current in the coils of the scanning magnet.…”
