Pencil beam coded aperture x-ray scatter imaging
Kenneth P. MacCabe,Kalyani Krishnamurthy,Amarpreet S. Chawla,Daniel L. Marks,Ehsan Samei,David J. Brady +5 more
TL;DR: In this article, coded aperture x-ray scatter imaging was used to interrogate scattering targets with a pencil beam using a flat-panel scintillation detector, and the results demonstrate that a single snapshot can be used to estimate scattering properties along an xray beam, and serve as a foundation for volumetric imaging of scattering objects.
Journal ArticleDOI
Compressive single-pixel snapshot x-ray diffraction imaging.
TL;DR: A coded aperture with subpixel features is employed to modulate the energy spectrum of coherently scattered photons and recover the object properties using an iterative inversion algorithm based on compressed sensing theory.
Journal ArticleDOI
Radioactive scandium in the youngest galactic supernova remnant g1.9+0.3
Kazimierz J. Borkowski,Stephen P. Reynolds,David A. Green,Una Hwang,Robert Petre,Kalyani Krishnamurthy,Rebecca Willett +6 more
TL;DR: In this article, the authors reported the discovery of thermal X-ray emission from the youngest Galactic supernova remnant G1.9+0.3, from a 237 ks Chandra observation.
Journal ArticleDOI
Snapshot molecular imaging using coded energy-sensitive detection
TL;DR: Results indicate a path toward real-time volumetric molecular imaging for non-destructive examination in a variety of applications, including medical diagnostics, quality inspection, and security detection.
Journal ArticleDOI
Expansion of the Youngest Galactic Supernova Remnant G1.9+0.3
Ashley Carlton,Kazimierz J. Borkowski,Stephen P. Reynolds,Una Hwang,Robert Petre,David A. Green,Kalyani Krishnamurthy,Rebecca Willett +7 more
TL;DR: In this paper, the authors measured the expansion and brightening of G1.9 + 0.3, the youngest supernova remnant, comparing Chandra X-ray images obtained in 2007 and 2009.
