Universal mask for hard X rays
David Ceddia, Alaleh Aminzadeh, Philip K. Cook +3
The penetrating power of X rays underpins important applications such as medical radiography. However, this same attribute makes it challenging to achieve flexible on-demand patter…
On the Inherent Dose-Reduction Potential of Classical Ghost Imaging
Andrew M. Kingston, Wilfred K. Fullagar, Glenn R. Myers +3
Classical ghost imaging is a computational imaging technique that employs patterned illumination. It is very similar in concept to the single-pixel camera in that an image may be r…
Neutron Ghost Imaging
Andrew M. Kingston, Glenn R. Myers, Daniele Pelliccia +4
Ghost imaging is demonstrated using a poly-energetic reactor source of thermal neutrons. The method presented enables position resolution to be incorporated, into a variety of neut…
X-ray ghost tomography: denoising, dose fractionation and mask considerations
Andrew M. Kingston, Glenn R. Myers, Daniele Pelliccia +2
Ghost imaging has recently been successfully achieved in the X-ray regime; due to the penetrating power of X-rays this immediately opens up the possibility of X-ray ghost tomograph…
