An intraoral imaging apparatus for tomosynthesis imaging has an x-ray source having a primary collimator that defines boundaries of a radiation field. A transport apparatus translates the x ray source along a path for tomographic imaging. An intraoral x-ray detector defines an imaging area for the radiation field. A positioning apparatus correlates the position of the intraoral detector to the position of a secondary collimator. One or more radio-opaque markers provided on a detector attachment is coupled to the detector, the one or more markers configured to condition acquired x-ray images to relate the spatial position of the intraoral x-ray detector to the x-ray source position, wherein the one or more markers are disposed within the defined imaging area. A control logic processor accepts image data from the detector and determines the relative location of the source with respect to the detector according to detected marker position.
