Journal ArticleDOI
Computed tomography of x-ray index of refraction using the diffraction enhanced imaging method.
F.A. Dilmanian,Zhong Zhong,B. Ren,X. Y. Wu,Leroy Dean Chapman,Itzhak Orion,William Thomlinson +6 more
TL;DR: Diffraction enhanced imaging is a new, synchrotron-based, x-ray radiography method that uses monochromatic, fan-shaped beams, with an analyser crystal positioned between the subject and the detector, and has the potential for use in clinical radiography and in industry.
Journal Article
Response of avian embryonic brain to spatially segmented x-ray microbeams
F.A. Dilmanian,Morris Gm,Le Duc G,Huang X,B. Ren,Tigran Bacarian,Allen Jc,John Kalef-Ezra,Itzhak Orion,Rosen Em,Sandhu T,Sathé P,X. Y. Wu,Zhong Zhong,H. L. Shivaprasad +14 more
TL;DR: Brain tolerance was estimated to be about three times higher to microbeam irradiation as compared with broad beam irradiation, as compared to the broad beam modality.
Journal ArticleDOI
The performance of a novel ion-counting nanodosimeter
G Garty,S. Shchemelinin,Amos Breskin,Rachel Chechik,G Assaf,Itzhak Orion,Vladimir Bashkirov,Reinhard W. Schulte,Bernd Grosswendt +8 more
TL;DR: In this article, the ion-counting nanodosimeter provides a precise measurement of the ionization distribution deposited within a small wall-less gas volume, modeling nanometer-scales of condensed matter, e.g. the DNA molecule.
Journal ArticleDOI
Monte Carlo simulation of dose distributions from a synchrotron-produced microplanar beam array using the EGS4 code system.
TL;DR: To design therapy parameters for tumour treatments, the newly upgraded LSCAT (Low energy SCATtering) package of the EGS4 Monte Carlo simulation code was adapted to develop an accurate self-written user code for calculating microbeam radiation dose profiles with a precision of 1 microm.
Journal ArticleDOI
MOSFET dosimetry of an X-ray microbeam
Anatoly B. Rosenfeld,G.I. Kaplan,Tomas Kron,Barry J. Allen,A. Dilmanian,Itzhak Orion,B. Ren,Michael L. F Lerch,A. Holmes-Siedle +8 more
TL;DR: In this paper, the role of the topology of the MOSFET gate oxide when mapping radiation microbeams was investigated and the results clearly demonstrate the superiority of the "edge-on" MOS-FET when applied to mapping of narrow radiation beams.
