Title: Observation of a Soft Tissue by a Zernike Phase Contrast Hard X-ray Microscope

Abstract

A Zernike-type phase contrast hard X-ray microscope was constructed at the Photon Factory BL3C2 (KEK). A white beam from a bending magnet was monochromatized by a silicon double crystal monochromator. Monochromatic parallel X-ray beam illuminated a sample, and transmitted and diffracted X-ray beams were imaged by a Fresnel zone plate (FZP) which had the outer zone width of 100 nm. A phase plate made of a thin aluminum foil with a pinhole was set at the back focal plane of the FZP. The phase plate modulated the diffraction beam from the FZP, whereas a direct beam passed through the pinhole. The resolution of the microscope was measured by observing a tantalum test pattern at an X-ray energy of 9 keV. A 100nm line-and-space pattern could be resolved. X-ray montage pictures of growing eggs of artemia (plankton) were obtained.

  • We developed an off-axis-illuminated zone-plate-based hard x-ray Zernike phase-contrast microscope beamline at Pohang Light Source. Owing to condenser optics-free and off-axis illumination, a large field of view was achieved. The pinhole-type Zernike phase plate affords high-contrast images of a cell with minimal artifacts such as the shade-off and halo effects. The setup, including the optics and the alignment, is simple and easy, and allows faster and easier imaging of large bio-samples.
  • The possibilities of using Zernike phase contrast in hard X rays for imaging micropipes in a silicon carbide single crystal are analyzed by numerical simulation. Calculations are performed for the experimental conditions characteristic of third-generation synchrotron radiation sources. A scheme is considered where the focusing element is a parabolic refracting lens and the phase-shifting element is mounted at the point of the source image. It is shown that micropipe cross sections by a beam with a longitudinal diameter reaching 10 {mu}m are imaged by the lens without distortions. At the same time, the lens makes it possible to magnify themore » image several tens of times. The cross sections that are significantly elongated along the beam are imaged with artifacts; however, their structure can also be recovered. It is shown that polychromaticity of radiation does not significantly affect the object imaging.« less
  • Differential phase-contrast scanning x-ray microscope/microtomography have been developed. A fast readout charge-coupled device (CCD) camera coupled with a visible-light conversion unit is used as a detector to record the transmitted intensity distribution of far-field image for every pixel in a scan. Simultaneous absorption and phase-contrast images are given from a single scan by image-processing of the CCD frames. The system is constructed at BL20XU of SPring-8, and its feasibility is demonstrated at the photon energy of 8 keV. A tantalum test chart is observed and its finest structure of 140 nm pitch pattern is clearly observed. Measured phase sensitivity ismore » approximately {lambda}/270. Some low-Z element specimens are observed and obtained phase contrast image shows much higher sensitivity than that of absorption contrast.« less
  • X-ray microscopy in the multi-keV photon energy range offers unique possibilities to study thick dense samples with high spatial resolution. When employing a high numerical aperture (N.A.) condenser zone plate sample illumination in combination with a high resolution micro zone plate objective lens, a spatial resolution of currently 60 nm is achieved. Since the absorption becomes smaller with increasing photon energy, phase contrast imaging overcomes the limitation for imaging weakly absorbing structures in amplitude contrast mode. We report here on X-ray microscopy of advanced microelectronic devices imaged in Zernike phase contrast mode. While the amplitude contrast between copper and siliconmore » dioxide in these samples is only 7 %, negative as well as positive phase contrast were demonstrated with a contrast of 40 % and 45 %, respectively.« less
  • Zernike phase contrast is a useful technique for nanoscale X-ray computed tomography (CT) imaging of materials with a low X-ray absorption coefficient. It enhances the image contrast by phase shifting X-ray waves to create changes in amplitude. However, it creates artifacts that hinder the use of traditional image segmentation techniques. We propose an image restoration method that models the X-ray phase contrast optics and the three-dimensional image reconstruction method. We generate artifact-free images through an optimization problem that inverts this model. Though similar approaches have been used for Zernike phase contrast in visible light microscopy, this optimization employs an effectivemore » edge detection method tailored to handle Zernike phase contrast artifacts. We characterize this optics-based restoration method by removing the artifacts in and thresholding multiple Zernike phase contrast X-ray CT images to produce segmented results that are consistent with the physical specimens. We quantitatively evaluate and compare our method to other segmentation techniques to demonstrate its high accuracy.« less
