Abstract: In illustrated laminographic embodiments, longitudinal body layers are scanned by arranging individual x-ray tubes along a path or surface parallel to the body layer. The intensity of each conical beam focused on the body layer may be individually selected according to the absorption of the associated beam path through the body, for the sake of a fluoroscopic image of uniform brightness. For scanning either longitudinal or transverse body layers, a stationary detector may be utilized, sequentially activated conical or thin fan-shaped beams impinging on respective sets of time-shared detector locations to provide sets of measured values identified with the respective beams.
