A non-free-space propagation x-ray phase contrast imaging method sensitive to phase effects in two directions simultaneously
- Abstract:
- We present an x-ray phase contrast imaging method based on coded apertures sensitive to phase effects in two directions simultaneously. To date, this is the only non-free-space propagation approach with this capability. Whereas the use of free-space propagation methods is limited to synchrotron radiation or microfocal x-ray sources, which impose severe limits in terms of practical applicability, coded-aperture based methods have been shown to provide synchrotronlike phase contrast enhancements with conventional x-ray sources. A two-directional sensitive method working with conventional sources could create a breakthrough in medical imaging, where two-directional sensitivity is often a mandatory requirement. © 2009 American Institute of Physics.
