Accurate measures of regional lung air volumes from chest X-rays of small animals
D. W. O'Connell, K. S. Morgan, G. Ruben +10
We present a robust technique for calculating regional volume changes within the lung from X-ray radiograph sequences captured during ventilation, without the use of computed tomog…
Precise phase retrieval for propagation-based images using discrete mathematics
J. A. Pollock, K. S. Morgan, L. C. P. Croton +5
The ill-posed problem of phase retrieval in optics, using one or more intensity measurements, has a multitude of applications using electromagnetic or matter waves. Many phase retr…
Full field X-ray Scatter Tomography
Gary Ruben, Isaac Pinar, Jeremy M. C. Brown +8
In X-ray imaging, photons are transmitted through and absorbed by the subject, but are also scattered in significant quantities. Previous attempts to use scattered photons for biol…
A simple, pixel-wise response correction for ring artifact removal in both absorption and phase contrast X-ray computed tomography
Linda C. P. Croton, Gary Ruben, Kaye S. Morgan +2
We present a pixel-specific, measurement-driven correction that effectively minimizes errors in detector response that give rise to the ring artifacts commonly seen in X-ray comput…
A route to non-Abelian quantum turbulence in spinor Bose-Einstein condensates
Thomas Mawson, Gary Ruben, Tapio Simula
We have studied computationally the collision dynamics of spin-2 Bose--Einstein condensates initially confined in a triple-well trap. Depending on the intra- and inter-component re…
Texture control in a pseudospin Bose-Einstein condensate
Gary Ruben, Michael J. Morgan, David M. Paganin
We describe a wavefunction engineering approach to the formation of textures in a two-component nonrotated Bose-Einstein condensate. By controlling the phases of wavepackets that c…
