Abstract
The present invention describes scintillator-elements for use in X-ray detectors, the elements being shaped to ensure maximum absorption of the energy carried in by X-ray photons and to provide high position-resolution. Arrangements of such scintillator-elements in arrays and detector-systems comprising a plurality of arrays are described.
Claims10
A scintillator block attached to a photodiode, the scintillator comprising a cylindrical cavity extending from the top surface towards the block-center, the cavity axis being substantially perpendicular to said top surface and the scintillator-block being coated with or surrounded by a layer of light-reflecting material which directs the light generated through X-ray absorption towards the uncoated surface which is attached to the photodiode.
An X-ray detector comprising a scintillator-plate, with a perforated metal-plate, wherein the scintillator-plate is provided with cylindrical cavities that originate from the scintillator-plate top-surface, the cavities being substantially perpendicular to said top-surface and the cavity-length being smaller than half the scintillator-plate thickness, and, wherein, the perforated metal-plate is made of lead, tungsten, copper or other highly-absorbing X-ray material and each metal-plate perforation is located above a scintillator-cavity opening.
