Title: X-ray grid-detector apparatus

Abstract

A hybrid grid-detector apparatus for x-ray systems wherein a microchannel plate structure has an air-interspaced grid portion and a phosphor/optical fluid-filled grid portion. The grids are defined by multiple adjacent channels separated by lead-glass septa. X-rays entering the air-interspaced grid portion at an angle of impingement upon the septa are attenuated, while non-impinging x-rays pass through to the phosphor/fluid filled portion. X-ray energy is converted to luminescent energy in the phosphor/fluid filled portion and the resultant beams of light are directed out of the phosphor/optical fluid filled portion to an imaging device.

High collection efficiency X-ray spectrometer system with integrated electron beam stop, electron detector and X-ray detector for use on electron-optical beam lines and microscopes

Patent Zaluzec, Nestor J.

An X-ray spectrometer systems and methods are provided for implementing signal detection for use on electron-optical beam lines and microscopes. The X-ray Spectrometer System (XSS) includes an X-ray detector (XD) measuring the X-ray signal and positioned proximate to a specimen. An environmental isolation window together with an electron beam stop is disposed between XD and the specimen. The environmental isolation window and the electron beam stop protect XD from electrons directly transmitted through the specimen. An electron detector is located between the electron beam stop and the specimen allowing the measurement of scattered electrons. The XD measures an X-ray signalmore » in the X-ray spectrometer system. « less

Air-core grid for scattered x-ray rejection

Patent Logan, Clinton M [Pleasanton, CA]; Lane, Stephen M [Oakland, CA]

The invention is directed to a grid used in x-ray imaging applications to block scattered radiation while allowing the desired imaging radiation to pass through, and to process for making the grid. The grid is composed of glass containing lead oxide, and eliminates the spacer material used in prior known grids, and is therefore, an air-core grid. The glass is arranged in a pattern so that a large fraction of the area is open allowing the imaging radiation to pass through. A small pore size is used and the grid has a thickness chosen to provide high scatter rejection. Formore » « less

High performance x-ray anti-scatter grid

Patent Logan, Clinton M [Pleasanton, CA]

An x-ray anti-scatter grid for x-ray imaging, particularly for screening mammography, and method for fabricating same, x-rays incident along a direct path pass through a grid composed of a plurality of parallel or crossed openings, microchannels, grooves, or slots etched in a substrate, such as silicon, having the walls of the microchannels or slots coated with a high opacity material, such as gold, while x-rays incident at angels with respect to the slots of the grid, arising from scatter, are blocked. The thickness of the substrate is dependent on the specific application of the grid, whereby a substrate of themore » « less

Fiber fed x-ray/gamma ray imaging apparatus

Patent Hailey, Charles J [San Francisco, CA]; Ziock, Klaus-Peter [Livermore, CA]

X-ray/gamma ray imaging apparatus is disclosed for detecting the position, energy, and intensity of x-ray/gamma ray radiation comprising scintillation means disposed in the path of such radiation and capable of generating photons in response to such radiation; first photodetection means optically bonded to the scintillation means and capable of generating an electrical signal indicative of the intensity, and energy of the radiation detected by the scintillation means; second photodetection means capable of generating an electrical signal indicative of the position of the radiation in the radiation pattern; and means for optically coupling the scintillation means to the second photodetection means.more » « less

X-ray and gamma ray detector readout system

Patent Tumer, Tumay O [Riverside, CA]; Clajus, Martin [Los Angeles, CA]; Visser, Gerard [Bloomington, IN]

A readout electronics scheme is under development for high resolution, compact PET (positron emission tomography) imagers based on LSO (lutetium ortho-oxysilicate, Lu.sub.2SiO.sub.5) scintillator and avalanche photodiode (APD) arrays. The key is to obtain sufficient timing and energy resolution at a low power level, less than about 30 mW per channel, including all required functions. To this end, a simple leading edge level crossing discriminator is used, in combination with a transimpedance preamplifier. The APD used has a gain of order 1,000, and an output noise current of several pA/ Hz, allowing bipolar technology to be used instead of CMOS, formore » « less
