Abstract
An apparatus includes a plurality of x-ray imaging detectors having at least a first x-ray imaging detector and a second x-ray imaging detector. The first and second x-ray imaging detectors are configured sequentially along an x-ray beam propagation direction.
Claims23
An apparatus comprising:
- at least one scintillator configured to allow first x-rays of an x-ray beam incident on the at least one scintillator to propagate through the at least one scintillator and to generate visible light in response to second x-rays of the x-ray beam;
- at least one optical lens system configured to allow a propagation of at least a first portion of the first x-rays through the at least one optical lens system and to relay at least some of the visible light to an image plane of the at least one optical lens system;
- at least one mirror configured to allow a propagation of at least a second portion of the first portion of the first x-rays through the at least one mirror and to reflect at least some of the visible light from the at least one optical lens system in a direction non-parallel relative to an x-ray propagation direction of the first x-rays propagating through the at least one optical lens system and the at least one mirror;
- and
- at least one optical detector system comprising a plurality of active elements at the image plane of the at least one optical lens system and configured to receive the visible light reflected by the at least one mirror.

- and
- a first optical detector system configured to receive at least some of the first visible light reflected by the first mirror, and to generate a first image in response to the received at least some of the first visible light.
