Abstract
X-ray imaging screens utilizing phosphors disposed in microchannels disposed in a plate. This application relates to the “tiling” of such microchannel plates to form a larger imaging area and to the use of “storage phosphors” in the microchannel plates which enables the phosphors to be read out after exposure and from the side exposed to the X-rays. The storage phosphor screens of the present invention provide significantly increased resolution than the prior art storage phosphor screens.
Claims16
A high resolution radiation imaging storage phosphor screen, comprising:
- a) a substrate having a planar surface;
- b) a multiplicity of microchannels extending into the surface of the substrate, each of said microchannels having a diameter of less than 40 microns,
- c) a multiplicity of storage phosphors disposed in each of said microchannels.
A high resolution radiation imaging phosphor screen, comprising:
- a) a base substrate having a mounting surface;
- b) a plurality of microchannel plates releasably secured to the mounting surface of the base substrate, each of said microchannel plates having a multiplicity of microchannels having a diameter of less than 40 microns, and
- c) a multiplicity of phosphors disposed in each of said microchannels.
