A system for acquiring image data of a subject with an imaging system, comprising: a gantry that completely annularly encompasses at least a portion of the subject; a source positioned within and movable relative to the gantry, the source responsive to a source signal to output at least one pulse; a multi-row detector positioned within and movable relative to the gantry, the multi-row detector positionable into alignment with the source to detect the at least one pulse emitted by the source and set multi-row detector data based on the detected at least one signal; a flat panel detector positioned within and movable relative to the gantry, the flat panel detector positionable into alignment with the source to detect the at least one pulse emitted by the source and set flat panel detector data based on the detected at least one signal; characterized for further comprising: a collimator positioned within and movable relative to the gantry, the collimator responsive to a collimator signal to shape the at least one pulse to only match the shape of the multi-row detector or of the flat panel detector; an image acquisition control module that sets the signal for the source and determines only one of the multi-row detector or the flat panel detector to use to detect the at least one pulse emitted by the source, wherein the image acquisition control module comprises an image control module that sets the source signal for the source and the collimator signal for the collimator. a gantry that completely annularly encompasses at least a portion of the subject; a source positioned within and movable relative to the gantry, the source responsive to a source signal to output at least one pulse; a multi-row detector positioned within and movable relative to the gantry, the multi-row detector positionable into alignment with the source to detect the at least one pulse emitted by the source and set multi-row detector data based on the detected at least one signal; a flat panel detector positioned within and movable relative to the gantry, the flat panel detector positionable into alignment with the source to detect the at least one pulse emitted by the source and set flat panel detector data based on the detected at least one signal; characterized for further comprising: a collimator positioned within and movable relative to the gantry, the collimator responsive to a collimator signal to shape the at least one pulse to only match the shape of the multi-row detector or of the flat panel detector; an image acquisition control module that sets the signal for the source and determines only one of the multi-row detector or the flat panel detector to use to detect the at least one pulse emitted by the source, wherein the image acquisition control module comprises an image control module that sets the source signal for the source and the collimator signal for the collimator. a collimator positioned within and movable relative to the gantry, the collimator responsive to a collimator signal to shape the at least one pulse to only match the shape of the multi-row detector or of the flat panel detector; an image acquisition control module that sets the signal for the source and determines only one of the multi-row detector or the flat panel detector to use to detect the at least one pulse emitted by the source, wherein the image acquisition control module comprises an image control module that sets the source signal for the source and the collimator signal for the collimator.
