X-Ray Imaging System And Method

摘要

An X-ray imaging system can include an X-ray source that projects a beam of X-ray radiation and an X-ray detector positioned to receive the beam of X-ray radiation at a location. The X-ray detector can include: (i) a monolithic substrate having a first side and a second side opposite the first side, (ii) a scintillation layer arranged upon the first side and including a first region and a second region, the first region having a first X-ray sensitivity and the second region having a second X-ray sensitivity different than the first X-ray sensitivity, and (iii) a photosensor array arranged upon the second side. The X-ray source and X-ray detector can be configured to adjust the location at which the X-ray detector receives the beam of X-ray radiation such that the location is primarily within the first region or the second region.

1. An X-ray imaging system, comprising:
an X-ray source configured to project a beam of radiation toward an object; a first filter arranged at the X-ray source to filter the beam of radiation prior to being received at a first region; a second filter arranged at the X-ray source to filter the beam of radiation prior to being received at a second region; and an X-ray detector positioned to receive the beam of radiation, the X-ray detector including:
a substrate having a first side and a second side,a scintillation layer on the first side of the substrate, the scintillation layer having the first region with a first X-ray sensitivity and the second region with a second X-ray sensitivity different than the first X-ray sensitivity, anda photosensor array on the second side of the substrate, the photosensor array having a first photosensor subarray that corresponds to the first region and a second photosensor subarray that corresponds to the second region, wherein the X-ray source and the X-ray detector are configured to adjust a location at which the X-ray detector receives the beam of radiation such that the location is at least partially within the first region or the second region.
