Patent ID: 8351568

Claim:
An apparatus for obtaining a long length x-ray image of a subject, comprising: a first x-ray detector comprising a first housing and a radiographic imaging array positioned within the first housing to receive incident radiation and output a signal corresponding thereto; a second x-ray detector comprising a second housing and a radiographic imaging array positioned within the second housing to receive incident radiation and output a signal corresponding thereto; an x-ray source having an exposure directing apparatus that is actuable to direct exposure from the x-ray source towards at least a first imaging position during a first interval and a second imaging position during a second interval, with an overlap along a boundary between the at least first and second imaging positions; an x-ray detector holder comprising a detector translation apparatus that is actuable to translate at least one of the first and second x-ray detectors along a length direction to an interim position for one of the first and second intervals and to either the first or the second imaging position for the other of the first and second intervals; and a host controller programmed to provide instructions for movement of the x-ray detector holder and exposure directing apparatus.
