Fourier transform based iterative method for x-ray differential phase-contrast computed tomography
X-ray phase-contrast tomography, x-ray refractive index, iterative reconstruction,interior tomography
2011/9/6
Biological soft tissues encountered in clinical and pre-clinical imaging mainly consist of light element atoms, and their composition is nearly uniform with little density variation. Thus,x-ray attenu...
Single shot phase contrast imaging using laser-produced Betatron x-ray beams
Betatron x-ray beams
2011/9/5
Development of x-ray phase contrast imaging applications with a laboratory scale source have been limited by the long exposure time needed to obtain one image. We demonstrate, using the Betatron x-ray...
Radio-over-Fibre Phase Contrast Imaging using a Reflective Electro-Absorption Transducer and 1550/1310nm VCSELs
Imaging systems Optical processing of radar images
2015/6/4
Radio-over-fibre phase contrast imaging is a new technique for object characterization in hostile environments. Commercially-available 1550nm/1310nm VCSELs and a reflective electro-absorption transduc...

Automated visual-tracking of cell population in vitro using
phase-contrast time-lapse microscopy is vital for the
quantitative and systematic study of cell behaviors, including
spatiotemporal quant...
X-Ray Phase-Contrast Imaging with Three 2D Gratings
X-Ray Phase-Contrast Imaging Three 2D Gratings
2009/9/4
X-ray imaging is of paramount importance for clinical and preclinical imaging but it is fundamentally restricted by the attenuation-based contrast mechanism, which has remained essentially the same si...
Direct Fan-Beam Reconstruction Algorithm via Filtered Backprojection for Differential Phase-Contrast Computed Tomography
Direct Fan-Beam Reconstruction Algorithm Filtered Backprojection Differential Phase-Contrast Computed Tomography
2009/9/4
Recently, a novel data acquisition method has been proposed and experimentally implemented for differential phase-contrast computed tomography (DPC-CT), in which a conventional X-ray tube and a Talbot...
Analysis of Cardiac Torsion by Strain Calculation with MR Phase-contrast Image
Heart Twist MR-PC Three-dimensional Analysis Medical Image
2009/6/1
Torsion movement of the left ventricle has significance in ventricle contraction and dilation. In this study, we propose methods of analyzing torsion movement of whole body and local region of left ve...
A New 3D Simulation Method for the Construction of Optical Phase Contrast Images of Gold Nanoparticle Clusters in Biological Cells
3D Simulation Method Optical Phase Contrast Images Gold Nanoparticle Clusters Biological Cells
2009/5/19
A new 3D simulation method based on the finite-difference time domain (FDTD) approach in combination with Fourier optic techniques is applied to the modeling of optical phase contrast microscope (OPCM...
Performance and comparison of CASA systems equipped with different phase-contrast optics
Human sperm motility sperm tracking
2009/2/12
Most computer-aided sperm analysis (CASA) systems for human spermatozoa use positive phase-contrast optics. In this study the performance of one of these (HTM) and two other systems using negative...
