Hybrid modulated-phase-grating for phase contrast x-ray for a varying fringe period clinical interferometry system
Year: 2022
Type: conference-paper
Abstract: A phase contrast system with a modulated phase grating (MPG) eliminates the need for an analyzer when compared to a standard Talbot Lau X-ray interferometer. This can provide three scans with the same total dose to the object as a standard mammogram. In this work, a hybrid MPG phase contrast system was investigated where the system fringe period can be varied, by changing a single system parameter, allowing interrogation at different resolutions and scatter lengths to further the variety of scans possible with the phase contrast system. The system can be also used for screening in a default setting.
