Angiography by Synchrotron Radiation

Clinical step onward with X-ray dark-field imaging and perspective view of medical applications of synchrotron radiation in Japan

“…Only intravenous coronary angiography is under way at two synchrotron facilities [44][45][46][47][48][49][50][51]. Because of the desire to visualize unseen organs, visible X-ray interferometry imaging by Momose et al [21,22] and other imaging projects which we have seen above are in progress.…”

“…The 35 keV X-ray energy was adopted because this has been utilized for intravenous coronary angiography program in Japan [44][45][46] where we have fixed just above the absorption edge of iodine 33.17 keV for the contrast agent. IVCAG using synchrotron radiation that was initiated by Rubenstein et al [47] is now very popular [48][49][50][51].…”

Radiation background and beam quality in secondary X-ray imaging for human angiography with Au as contrast agent

“…That made it possible to develop previously unavailable powerful imaging techniques. Two of these methods are especially ingenious: The K-Edge Subtraction (KES) technique [1][2][3][4][5][6][7], and Dual Photon Absorbtiometry (DPA) [7]. Both are based on transluminating the target with X-rays, and then observing the shadow image generated by absorption of X-rays in the target.…”

“…Nevertheless, in this paper we will not assume any energy discrimination capability for the detector. 1 Instead, we consider what can be accomplished by position/momentum selection, energy or time filtering, and combinations thereof.…”

Development of a two-dimensional imaging system for clinical applications of intravenous coronary angiography using intense synchrotron radiation produced by a multipole wiggler

“…Rubenstein et al (1987) succeeded in a clinical application of the one-dimensional scanning system for the ®rst time in 1986. Since then, many clinical applications of a one-dimensional scanning system have been established at SSRL, NSLS and DESY.…”
