Journal ArticleDOI
The application of synchrotron radiation to non-invasive angiography☆
E. B. Hughes,H. D. Zeman,L. E. Campbell,Robert Hofstadter,U. Meyer-Berkhout,J. N. Otis,J. Rolfe,J. P. Stone,S. L. Wilson,Edward Rubenstein,Donald C. Harrison,R. S. Kernoff,A.C. Thompson,George Brown +13 more
TL;DR: Synchrotron radiation provides a new source of X-rays highly-suited to iodine K-edge Digital Subtraction Angiography (DSA) and offers the prospect of visualizing arteries, and in particular the coronary arteries, by peripheral venous injection.
Journal ArticleDOI

Y. Chan,R. A. Partridge,C. W. Peck,W. Kollman,M. Richardson,K. Strauch,D. Aschman,D. G. Coyne,B. L. Beron,R.L. Carrington,R. A. Eichler,R. Hofstadter,E. B. Hughes,G. I. Kirkbride,A. Liberman,J. O'Reilly,R. Parks,J. Rolfe,J.W. Simpson,J. Tompkins,A. Baumgarten,J. Bernstein,Elliott D. Bloom,F. Bulos,J. Dillon,J. Gaiser,G. Godfrey,J. Hall,C. Kiesling,M. Oreglia,D. Pfau,H. Royden +31 more
TL;DR: The Cluster of 54 detector as mentioned in this paper is the predecessor of the Crystal Ball detector, which is designed for the study of electron-positron collisions at colliding beam facilities, and it has been successfully tested.
Journal ArticleDOI
Evaluation of synchrotron X-rays for transvenous coronary angiography
H. D. Zeman,E. B. Hughes,L. Campbell Finman,Robert Hofstadter,A. Hudson,J. N. Otis,J. Rolfe,Edward Rubenstein,Donald C. Harrison,R. S. Kernoff,A.C. Thompson,George Brown +11 more
TL;DR: An evaluation of synchrotron radiation for the non-invasive assessment of coronary artery disease in humans and the probable configuration of an expanded system for pilot human subject studies is described.
Journal ArticleDOI
On the detection of 50 MeV γ-rays with a large modularized NaI(Tl) detector
R.L. Carrington,R. A. Eichler,R. Hofstadter,E. B. Hughes,J. Rolfe,T.P. McPharlin,J. D. Bowman,M. D. Cooper,M.E. Hamm,C. M. Hoffman,R. E. Mischke,D. E. Nagle,J. S. Sarracino,P. A. Thompson,Herbert L. Anderson,W. W. Kinnison,H. S. Matis,S. C. Wright +17 more
TL;DR: An array of 45 NaI(Tl) crystals modules, each in 20 in. in length and hexagonal in cross section with six 3 in. sides, has been operated as a detector of 50 MeV γ-rays in a search for the decay μ + →e + γ as mentioned in this paper.
Journal ArticleDOI

A.C. Thompson,Frederick S. Goulding,H. A. Sommer,J. T. Walton,E. B. Hughes,J. Rolfe,H. D. Zeman +6 more
TL;DR: A 30-element Si(Li) detector has been fabricated to measure the one-dimensional flux profile of 33 KeV x-rays from a synchrotron radiation beam as mentioned in this paper.
