Abstract
An X-ray detector that includes a sensor matrix and a scintillator arrangement and in which wire elements are spaced apart in layers A and B in order to reduce the crosstalk in neighboring detector elements. Scintillators are inserted at least partly in the grid openings formed.
Claims17
An X-ray detector which includes a sensor matrix and a scintillator arrangement comprising an anti-scatter grid, wherein the anti-scatter grid consists entirely of a plurality of overlapping layers of wire elements, spaced apart, and arranged to receive scintillators at least partly between the wire elements.
A scintillator arrangement which minimizes crosstalk of scattered radiation, consisting of:
- a plurality of layers of wire elements that are spaced apart and interwoven as a grid which is segmented in two directions in space and arranged to receive scintillators at least partly between the wire elements;
- and
- scintillator material provided at least party between the wire elements.
An X-ray detector, comprising:
- a plurality of layers of wire elements constructed to form a grid structure, wherein each layer is comprised of parallel wire elements, wherein the wire elements of adjacent layers run perpendicular to each other, resulting in openings within the grid between the perpendicular wires of adjacent layers;
- a plurality of scintillators, wherein one scintillator is located in each opening in the grid;
- and
- a sensor matrix positioned beneath the layers of wire elements and such that the plurality of layers of wire elements is between a radiation source and the sensor matrix, and performs a function of minimizing crosstalk between the scintillators which is known to result from scattered radiation.
