Driving of an x-ray detector to compensate for cross scatter in an x-ray imaging apparatus

An X-ray detector for imaging an object, wherein, the X-ray detector comprises a plurality of X-ray detecting areas, the plurality of X-ray detecting areas comprising a first area comprising a plurality of first pixels and a second area comprising a plurality of second pixels;

• wherein first radiation emitted by at least one X-ray source is received by at least a portion of the first pixels, and second radiation emitted by the at least one X-ray source is received by at least a portion of the second pixels, and the first radiation is a pulse of radiation and the second radiation is another pulse of radiation that is different than the first radiation, wherein the X-ray detector is configured such that the X-ray radiation received by a pixel leads to the generation of signal in that pixel;
• wherein the X-ray detector comprises at least one first plurality of storage nodes associated with the first area and at least one second plurality of storage nodes associated with the second area, wherein the at least one first plurality of storage nodes is configured to store a plurality of first signals representative of corresponding signals on the plurality of first pixels and the at least one second plurality of storage nodes is configured to store a plurality of second signals representative of corresponding signals on the plurality of second pixels;
• wherein, the at least one second plurality of storage nodes is configured to store the plurality of second signals after the at least one first plurality of storage nodes is configured to store the plurality of first signals;
• and
• wherein the X-ray detector comprises at least one reset, the at least one reset configured to reset the plurality of first pixels and configured to reset the plurality of second pixels, wherein the X-ray detector is configured such that the first radiation emitted by the at least one X-ray source is receivable by the portion of first pixels before the at least one reset resets the plurality of second pixels and the detector is configured such that the at least one reset resets the plurality of second pixels before the second radiation emitted by the at least one X-ray source is receivable by the portion of second pixels.

A method for imaging an object, comprising:

• receiving by at least a portion of first pixels of a first area of an X-ray detector first radiation emitted by at least one X-ray source, and the first radiation is a pulse of radiation, wherein the X-ray detector is configured such that X-ray radiation received by a pixel leads to the generation of signal in that pixel;
• storing, in at least one first plurality of storage nodes associated with the first area, a plurality of first signals representative of corresponding signals on the plurality of first pixels;
• resetting the plurality of second pixels;
• receiving by at least a portion of second pixels of a second area of the X-ray detector second radiation emitted by the at least one X-ray source, and the second radiation is a pulse of radiation that is different than the first radiation;
• and
• storing, in at least one second plurality of storage nodes associated with the second area, a plurality of second signals representative of corresponding signals on the plurality of second pixels.

• receiving by at least a portion of first pixels of a first area of an X-ray detector first radiation emitted by at least one X-ray source, and the first radiation is a pulse of radiation, wherein the X-ray detector is configured such that X-ray radiation received by a pixel leads to the generation of signal in that pixel;
• storing, in at least one first plurality of storage nodes associated with the first area, a plurality of first signals representative of corresponding signals on the plurality of first pixels;
• resetting the plurality of second pixels;
• receiving by at least a portion of second pixels of a second area of the X-ray detector second radiation emitted by the at least one X-ray source, and the second radiation is a pulse of radiation that is different than the first radiation;
• and
• storing, in at least one second plurality of storage nodes associated with the second area, a plurality of second signals representative of corresponding signals on the plurality of second pixel.
