Abstract: Various methods and systems are provided for x-ray field alignment. In one embodiment, a system includes a plurality of scintillation detectors distributed about edges of a light field associated with an x-ray field, a detector interface in communication with the plurality of scintillation detectors, and a computing device in communication with the detector interface. The detector interface configured to simultaneously obtain exposure data for the plurality of scintillation detectors and the computing device configured to determine an alignment distance between the light field and the x-ray field based at least in part upon the exposure data. In another embodiment, a method includes obtaining exposure data from a plurality of scintillation detectors distributed about edges of a light field during irradiation by an x-ray field and determining an alignment distance between the light field and the x-ray field based at least in part upon the exposure data.
