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.

Abstract: A photonic structure for “white” light generation by phosphors under the excitation of a LED. The photonic structure mounts the LED and an optically transparent nanocomposite matrix having dispersed therein phosphors which will emit light under the excitation of the radiation of the LED. The phosphors dispersed in the matrix may be nanocrystalline, or larger sized with the addition of non light emitting, non light scattering nanoparticles dispersed within the matrix material so as to match the index of refraction of the matrix material to that of the phosphors. The nanocomposite matrix material may be readily formed by molding and formed into a variety of shapes including lenses for focusing the emitted light. A large number of the photonic structures may be arranged on a substrate to provide even illumination or other purposes.

Abstract: An X-ray imaging system utilizing a pixelated X-ray source and a X-ray imaging detector operated synchronously. The imaging system may be used in industrial and medical applications. The X-ray source and X-ray detector are synchronized such that a corresponding area of the X-ray detector is activated when the corresponding area of the X-ray source is emitting X-rays. Synchronized and adaptive emission and detection of the X-rays results in scatter rejection, improved image quality, and optimum exposure and dose reduction.
