Abstract
The present invention discloses an ionizing radiation sensitive multi-layer structure having a charge accepting outer surface and comprising a conductive layer, said ionizing radiation sensitive multi-layer structure being operative such that imagewise ionizing radiation impinging on said ionizing radiation sensitive multi-layer structure causes a charge distribution, representing said imagewise ionizing radiation, to be formed in said conductive layer; and readout electronics coupled to said conductive layer to detect the charge distribution formed in said conductive layer.
Claims48
A radiation detection module comprising:
- an ionizing radiation sensitive multi-layer structure having a charge pattern accepting and retaining outer surface and comprising a conductive layer, said ionizing radiation sensitive multi-layer structure being operative such that imagewise ionizing radiation impinging on said ionizing radiation sensitive multi-layer structure causes a charge distribution, representing said imagewise ionizing radiation, to be formed in said conductive layer;
- and
- readout electronics coupled to said conductive layer to detect the charge distribution formed in said conductive layer.
An addressable array of radiation detection elements comprising:
- a radiation sensitive layered stack;
- a plurality of electronically addressable conductive columns associated with the radiation sensitive layered stack;
- readout electronics coupled to said plurality of electronically addressable conductive columns;
- and
- a charge injector, which scans the conductive columns, providing sequential row addressing of the array of radiation detection elements.
A module for detection of ionizing radiation images, the module comprising:
- an ionizing radiation receiving substrate arranged to receive an ionizing radiation image, said substrate including at least one segmented layer, that is segmented in a single dimension along a single segmentation axis, and at least one non-segmented layer;
- and
- an elongate scanning charge injector operative in association with said ionizing radiation receiving substrate for scanning said substrate along a scanning axis which is generally perpendicular to said segmentation axis.
A method for radiation detection employing an addressable array of radiation detection elements comprising:
- providing a radiation sensitive layered stack, a plurality of electronically addressable conductive columns associated with the radiation sensitive layered stack, and readout electronics coupled to said plurality of electronically addressable conductive columns;
- and
- employing a charge injector to scan the conductive columns, providing sequential row addressing of the array of radiation detection elements, thereby detecting said radiation via said readout electronics.
A method for radiation detection, the method comprising:
- providing an ionizing radiation sensitive multi-layer structure having a charge pattern accepting and retaining outer surface and comprising a conductive layer coupled to readout electronics;
- sensitizing said ionizing radiation sensitive multi-layer structure;
- and
- exposing said sensitized ionizing radiation sensitive multi-Layer structure to impinging ionizing radiation, thereby causing a readable charge distribution, representing said impinging ionizing radiation, to be formed in said conductive layer.
