Notes:
A position sensitive one-dimensional x-ray detector with a large dynamic range ((approximately-greater-than)214:1) for high photon fluxes with fast image recording sequence (300 ms per frame) has been developed for transvenous coronary angiography with synchrotron radiation. A position resolution of 1 LP/mm and a detection quantum efficiency (DQE) of at least 58% (for 11 000 photons per pixel) has been achieved for 33 keV photons in a Xe-CO2 gas mixture at 20 bars. The use of Kr-CO2 as conversion gas provides a better contrast of the weak iodine signal than Xe-CO2 or Si, respectively, for a fraction of 2% of the second harmonics of the synchrotron beam used. © 1995 American Institute of Physics.
