Abstract
An electronradiography imaging chamber providing a real time visual image. An electronradiography imaging chamber with a solid X-ray absorber at one electrode and with electrophoretic particles in the gap between the electrodes, with the particles being selectively moved to a transparent electrode as a result of the electrostatic charge image formed by absorption of incoming X-ray radiation in the solid absorber. An imaging chamber which can be cyclically operated at a relatively high repetition rate, typically 10 to 20 images per second, thereby providing real time viewing of the objects. SU PAC BACKGROUND OF THE INVENTION This invention relates to electronradiography and in particular, to X-ray systems providing for real time imaging. The present invention is an improvement on that disclosed in copending application entitled X-RAY SYSTEM WITH ELECTROPHORETIC IMAGING, Ser. No. 571,220, filed Apr. 24, 1975, now U.S. Pat. No. 3,965,352. In the aforesaid copending application, an electronradiography imaging chamber has first and second electrodes mounted in spaced relation with a gap therebetween, with a fluid in the gap. The fluid is an X-ray absorber which emits electrons and posit…
