Abstract
An X-ray imaging system includes an X-ray detector; a plurality of X-ray sources configured to illuminate the X-ray detector from different perspectives; a shutter in a transmission plane between each X-ray source controlling transmission of X-rays from each X-ray source to the X-ray detector; and a processor configured to receive and process X-ray data from the X-ray detector. The shutter may be configured to illuminate the X-ray detector alternately with each X-ray source. The processor may determine 3D information about an object from the processed X-ray data. Also provided are methods for processing X-ray data and different embodiments of shutters to alternately illuminate X-ray detectors.
Claims18
An X-ray imaging system, including:
- a. an X-ray detector,
- b. a plurality of X-ray sources, each X-ray source configured to illuminate the X-ray detector from a different perspective,
- c. a shutter in a transmission plane between each X-ray source and the X-ray detector, wherein the shutter controls a transmission of X-rays from each X-ray source through the transmission plane to the X-ray detector,
- d. a processor in communication with the X-ray detector for receiving and processing X-ray data received from the X-ray detector, and
- e. a conveyor configured to convey an object through the transmission plane;
- wherein the X-ray imaging system is configured to image the object when the object is positioned between the shutter and the X-ray detector;
- and
- wherein the plurality of X-ray sources comprises two X-ray sources, wherein the shutter alternatingly allows the transmission of X-rays from the two X-ray sources through the transmission plane.
An X-ray imaging system, including:
- a. an X-ray detector,
- b. a plurality of X-ray sources, each X-ray source configured to illuminate the X-ray detector from a different perspective,
- c. a shutter in a transmission plane between each X-ray source and the X-ray detector, wherein the shutter controls a transmission of X-rays from each X-ray source through the transmission plane to the X-ray detector,
- d. a processor in communication with the X-ray detector for receiving and processing X-ray data received from the X-ray detector, and
- e. a conveyor configured to convey an object through the transmission plane;
- wherein the X-ray imaging system is configured to image the object when the object is positioned between the shutter and the X-ray detector;
- and
- wherein the processor is configured to develop depth, height, and width information based on an analysis of X-ray images received from the X-ray detector.
An X-ray shutter for controlling a passage of X-rays in a transmission plane through the X-ray shutter, the X-ray shutter comprising:
- a body defining a plurality of transmission paths configured to allow X-rays generated by different X-ray sources at different positions in the transmission plane to pass through a respective transmission path;
- wherein the body is configured such that at most one transmission path of the plurality of transmission paths is aligned with the transmission plane at any time;
- and
- wherein the plurality of transmission paths are alternately aligned with the transmission plane.
