Tiled digital radiography detectors for long-length imaging

A method of capturing a long length radiographic image of a subject, the method comprising:

• arranging a plurality of radiographic detectors in a partially overlapping arrangement, wherein the plurality of radiographic detectors each include an imaging array layer, and wherein the imaging array layer in each of the plurality of radiographic detectors overlap, or are overlapped by, another imaging array layer in another radiographic detector such that a portion of the imaging array layer in each of the plurality of radiographic detectors is in front of, or behind, a portion of an imaging array layer in another radiographic detector with respect to a position of an x-ray source;
• receiving a ready signal from one or more of the plurality of radiographic detectors at a host system;
• activating the x-ray source using an activation signal transmitted by the host system in response to the ready signal;
• exposing a subject to x-rays from the activated x-ray source;
• simultaneously capturing a radiographic image of a different portion of the subject in each of the plurality of radiographic detectors;
• and
• receiving the plurality of captured radiographic images of the different portions of the subject at the host system;
• and
• aligning and digitally stitching together the plurality of captured radiographic images of the different portions of the subject at the host system to form the long length radiographic image of the subject.
