Spherical electrode X:ray imaging chamber - has low absorption window consists of two plates with spherical curvature stressed in compression and tension

摘要

An imaging chamber for a radiographic system is used for exposing an image receptor sheet to an X-ray source. A chamber with an X-ray window has low and uniform X-ray absorption and is substantially rigid for maintaining a uniform gap spacing between the electrodes with a high pressure in the gap. A window consists of inner and outer plates joined at the sides and a space between the sides with a compression resistant filler, with one plate stressed in compression and the other stressed in tension. A chamber uses the X-ray absorbing gas to press the receptor sheet against an electrode to achieve the desired sheet configuration.
