Arrayed X-ray source and X-ray imaging apparatus

An arrayed X-ray source, comprising a housing and a plurality of X-ray generators located within the housing, the plurality of X-ray generators being arranged in an array, the plurality of X-ray generators being provided separately from each other and configured to emit X-rays independently of each other,

• wherein the plurality of X-ray generators at least comprise a first row of X-ray generators and a second row of X-ray generators arranged parallel in a column direction of the array, the first row of X-ray generators and the second row of X-ray generators are arranged linearly in a row direction of the array, and the first row of X-ray generators and the second row of X-ray generators are offset from each other in the row direction of the array,
• wherein each of the plurality of X-ray generators comprises:
• an anode target configured to generate X-rays under an impact of an electron beam, and
• an X-ray extraction window, the X-ray extraction window being provided on the anode target such that at least a portion of the X-rays generated by the anode target is emitted from the X-ray extraction window,
• wherein X-ray extraction windows of the plurality of X-ray generators are all oriented toward a first direction,
• wherein the plurality of X-ray generators are arranged linearly in the housing in a second direction, with their anode targets being located on a same side,
• and wherein the anode targets of the first row of X-ray generators and the second row of X-ray generators are facing each other.
