This article presents the data of using three phase-based X-ray imaging techniques to characterize biomaterial scaffold and soft tissues in situ, as reported in our study "Low-dose phase-based X-ray imaging techniques for in situ soft tissue engineering assessments" [1]. The examined parameters include the radiation dose, scan time, and image quality, which are all critical to longitudinal in s...

The main purpose of this paper is to introduce 3D integral imaging interpolation method, to overcome the 3D missing information problem occurred between cylindrical lenses (micro-images) due to occluded areas in the previous cylindrical lens, new cylindrical lens shows an area, to generate one single photo-realistic 3D integral imaging frame. The method is based on a Multiprocessor ray-tracer c...

Up to now standard X-ray imaging technologies, rely primarily on the amplitude properties of the incident radiation, and do not depend on its phase. This is unchanged since Röntgen's discovery [1] that the intensity of an X-ray beam, as measured by the exposure on a film or an equivalent X-ray detection device, was related to the relative transmission properties of an object. However, the new i...

Due to their low cost, flexibility, and convenience for long distance data transfer, plastic scintillating fibers (PSFs) have been increasingly used in building detectors or sensors for detecting various radiations and imaging. In this work, the possibility of using PSF coupled with charge-coupled devices (CCD) to build area detectors for X-ray imaging is studied using a Monte Carlo simulation....

This pathway describes the development of soft gamma-ray/hard x-ray detector arrays at NASA’s Goddard Space Flight Center (GSFC, or Goddard), through a collaboration between the gamma-ray spectroscopy group and the detector branch. The Cadmium Zinc Telluride (CdZnTe, or CZT) detectors which resulted from this decade-long development were first flown on the wildly successful SWIFT mission in 200...

Micro X-ray fluorescence ~MXRF! offers the analyst a new approach to materials characterization. The range of applications is expanding rapidly. Single point analysis has been demonstrated for nanoliter volumes with detection limits at the 0.5 ng level. MXRF can be used as an element specific detector for capillary electrophoresis. Elemental imaging applications include analysis of sample corro...

For detailed biomedical observations using the optimum phase-contrast x-ray imaging, quantitative comparisons of imaging performances of two major imaging methods--x-ray interferometric imaging (XII) and diffraction enhanced imaging (DEI)--were performed. Density sensitivity and spatial resolution of each imaging method were evaluated using phantom tomograms obtained by each method with the sam...

X-ray imaging techniques that capture variations in the x-ray phase can yield higher contrast images with lower x-ray dose than is possible with conventional absorption radiography. However, the extraction of phase information is often more difficult than the extraction of absorption information and requires a more sophisticated experimental arrangement. We here report a method for three-dimens...
