The number of applications and technical implementations of X-ray phase-contrast imaging (XPCi) has continuously increased over the last two decades. As imaging detectors are insensitive to the phase of X-ray waves, various techniques were developed to transform sample-induced phase modulations into intensity modulations on the detector. For all these XPCi techniques the image formation...

Particle therapy is an established method to treat deep-seated tumours using accelerator-produced ion beams. For treatment planning, the precise knowledge of the stopping power (SP) within the patient is vital. Currently, SP values are extrapolated from X-ray CT, thus introducing conversion errors, eventually leading to uncertainties in the applied dose distribution. Using a proton computed...
