Title: Development and Applications of a Phase Contrast Imaging and Tomography Facility (PCIT) at Singapore Synchrotron Light Source

Abstract

Recent results achieved at an existing phase contrast imaging and tomography (PCIT) beamline at the Singapore Synchrotron Light Source (SSLS) have shown that high resolution of 2-dimensional (2D) and 3-dimensional (3D) imaging with a high resolution ({approx}2 {mu}m) can be an extremely useful tool for advanced materials characterization. With white radiation it was possible to obtain a high photon flux that can be exploited for real time radiology (100 ms per frame) together with high lateral resolution and high speed in 2D imaging and 3D tomography. Edge enhancement was also demonstrated.

  • 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.
  • An ultrafast, laser-driven x-ray source with a liquid mercury target has been used for phase contrast imaging of an excised murine liver and for computed tomography of an electronic component. The x-ray spectrum emitted at 5 kHz repetition rate is found to be similar to that of a 2.5 W, 30 kV microfocus x-ray tube with a tungsten anode. The images of the excised liver show the venous network with approximately 20 {mu}m spatial resolution. Phase contrast features in the tomographic images of the electronic component, transferred to the orthogonal cross sections upon reconstruction, show the internal components of themore » device with high contrast. Adequate signal-to-noise ratios in the images were achieved with exposure times between 1 and 3 min.« less
  • Phase-contrast imaging at laboratory-based x-ray sources using grating interferometers has been developed over the last few years for x-ray energies of up to 28 keV. Here, we show first phase-contrast projection and tomographic images recorded at significantly higher x-ray energies, produced by an x-ray tube source operated at 100 kV acceleration voltage. We find our measured tomographic phase images in good agreement with tabulated data. The extension of phase-contrast imaging to this significantly higher x-ray energy opens up many applications of the technique in medicine and industrial nondestructive testing.
