A system and a method for acquiring image data of a subject with an imaging system are provided. The system can include a gantry that completely annularly encompasses at least a portion of the subject, and a source positioned within the gantry. The source can be responsive to a signal to output at least one pulse. The system can include a multi-row detector positioned within the gantry. The multi-row detector can be in alignment with the source and sets multi-row detector data based on the detected at least one signal. The system can include a flat panel detector positioned within the gantry. The flat panel detector can in alignment with the source and sets flat panel detector data based on the detected at least one signal. The system can include an image acquisition control module that determines which of the multi-row detector and the flat panel detector to use.
