Multi-linear X-ray scanning systems and methods for X-ray scanning

摘要

An x-ray scanner includes an x-ray source producing a fan of x-rays, an x-ray detector array, a collimator disposed between the source and the array, fixed to the source, and defining a slit collimating the fan of x-rays into a linear x-ray beam. The array is spaced from the source such that a linear extent of the linear x-ray beam is no greater than a detector dimension of the array. An x-ray processing unit processes detection of the linear x-ray beam by the array. A processor-controlled motor moves the x-ray source about a source movement axis to pan the linear x-ray beam and create an x-ray emission cone and moves the array correspondingly with the source. The x-ray processing unit form an x-ray scanned image of an object disposed between the collimator and the array within the x-ray emission cone when the linear x-ray beam is panned across the object.

1. A scanning transmission x-ray imaging system, comprising:
an x-ray source producing x-rays at a focal spot and moving about a source movement axis passing through the focal spot; at least two x-ray detector arrays each having a detector dimension and detecting x-rays from the x-ray source along the detector dimension; a collimator disposed between the x-ray source and the at least two detector arrays, fixed to the x-ray source, and defining at least two slits to collimate the x-rays into a set of linear x-ray beams; the at least two x-ray detector arrays being spaced from the x-ray source such that the linear x-ray beam at each of the at least two x-ray detector arrays has the linear x-ray beam substantially impact within the height and width of a respective one of the at least two x-ray detector arrays; and
the at least two x-ray detector arrays moving correspondingly with the x-ray source such that each of the linear x-ray beams remain aligned with a respective one of the at least two x-ray detector arrays.
