Paper Abstract

X-ray phase imaging has found limited clinical use due to requirements on x-ray coherence that may not be easily translated to clinical practice. Instead, this work employs a conventional source to create structured illumination with a simple wire mesh. A mesh-shifting algorithm that incorporates deconvolution of the source spot width is used to enhance resolution. Polycapillary optics are employed to enhance coherence. The effects of incorporating optics with two different focal lengths are compared. Measurements of fat embedded artificial tumors have been performed.
