TL;DR: The results suggest that MIR is capable of operating at low photon count levels, therefore the method shows promise for use with conventional x-ray sources, and shows that, in addition to producing new types of object descriptions, MIR produces substantially more accurate images than its predecessor, DEI.

Diffraction enhanced x-ray imaging of articular cartilage
Leroy Dean Chapman,M.O. Hasnah,Oral Oltulu,Zhong Zhong,Juergen Mollenhauer,Carol Muehleman,Klaus E. Kuettner,Matthias Aurich,Etta D. Pisano,R. Eugene Johnston,William Thomlinson,Dale E. Sayers +11 more
TL;DR: In this article, a method and system for detecting an image of an object, particularly a soft tissue material, was proposed, where a generated x-ray beam is transmitted through the soft tissue materials.
Journal ArticleDOI
Extraction of extinction, refraction and absorption properties in diffraction enhanced imaging
TL;DR: In this paper, a more general method of determining independently the refraction, absorption and extinction properties of the object is presented, which is used to model the transmission, refraction and scatter distribution of the sample and to visualize these three physical phenomena separately.
Journal ArticleDOI
Diffraction enhanced imaging contrast mechanisms in breast cancer specimens
M.O. Hasnah,Zhong Zhong,Oral Oltulu,Etta D. Pisano,R. E. Johnston,Dale E. Sayers,W. Thomlinson,Dean Chapman +7 more
TL;DR: The density difference of fibrils in breast cancer as measured by absorption images correlate well with the density difference derived from refraction angle images of DEI, and theDEI apparent absorption image and the image obtained with the DEI system at the top of the reflectivity curve have much greater contrast than that of the normal radiograph.
Journal ArticleDOI
A new vibrational study of Acetazolamide compound based on normal coordinate analysis and DFT calculations
TL;DR: In this article, the 5-acetamido-1,3,4-thiadiazole-2-sulphonamide compound was characterized by infrared and Raman spectroscopy in the solid phase.
